I'm dumb as a brick and just want to make sure that I'm getting this right. Is the information in this link saying that L-Carnitine has a pH of 6.5 to 8 when mixed in a solution of 50 grams L-Carnitine to 1 liter of water?

No, it's saying this is a solution for sale that has L-Carnitine dissolved in water, and that water itself has a pH of 6-5 to 8.5 at a ratio of 50g/L. The relative neutrality of the solution is important because this is being sold as a reagent for synthesis, but a solution of L-Carnitine could have a totally different pH, because the pH of water is not determined (directly) by what's dissolved in it, but by the presence of free ions and/or proton donors. I don't know what effect putting L-Carnitine directly in a completely neutral solution would have on its pH, but at the very least this isn't making the claim that it would be between 6.5-8.5 if you did so, just that this solution happens to be within that range.

Well, from what I can tell, Carnitine in its ground racemic state isn't ionic or a proton donor (but someone who knows for sure should correct me if that's wrong)-- which means it doesn't have a pH at all. pH is a measure of the electrical properties of water, so anything that isn't water nor has a free ion nor is a proton donor doesn't participate in the pH system (directly, again, since they might catalyze something else that does effect pH, particularly in a living organism.)

Well, humans aren't made of bacterial mats, so no, my suggestion was robots that consume human poop for nutrients and breathe human exhale to fix carbon into sucrose. Like all lifeforms, they would only engage in the behaviors they were programmed to do, so if we gave them the instinct to fear and obey humans, they would. However, even if they went out of control and killed off humanity, they would do more for balancing the ecosystem in that than we've ever done. From the standpoint of survival for life on earth, it's a win-win scenario.

I was looking up how to extract DMT and apparently it's most commonly done with Mimosa Hostilis root bark. Looking at the guides it's very MacGyver tier. I'm saying I'm wondering if there is a more professional way of doing it. Essentially I'm asking, if you ever looked into extracting DMT and if you have the chemistry background, what methods of extraction do you prefer/recommend and do you have any advice regarding it? Perhaps a mistake that commonly diminishes the quality of the extraction or some deviation from the existing guides to end up with something more pure.

Rotovaps make chemistry much, much, much easier. That's a device that evaporates solvents very quickly.

Solvent choice is also very helpful. The amateur has to choose between a few commonly available solvents meant for shit like paint-stripping. Professionals can choose a solvent that has analytical standards, and is harder to obtain (can't get at the hardware store).

Pros also have better filtration systems. This is less expensive than the rotovap, and not as much as a time save, but still very helpful.

TLC plates help keep track of whether or not product is there (so you can be more efficient when pulling).

Better ventilation is nice.

Lab freezers are better than home freezers, and usually have safeguards to prevent blowing up.

In the end, if you have white crystals, it's a reasonably pure product. Crystallization is cool like that. However, a well-stocked lab will get higher yields in less time.

TLC is most often distribution chromatography ( with a smidgeon of absorption chromatography) , meaning its more about polarity of the substances than about their weight itself (though there often is an indirect relation between weight to affinity). you basically have a solvation hull on your substrate and the mobile phase flows above that, depending on the polarity of a substance it moves between the stationary and the mobile phase, thus seperating from other substances. ive made a nice animation for that shit but im too paranoid, ill see if i find a comparable animation

in theory you should get one band per compound of your mixture but high concentrations or an unsuitable eluent may lead to streaking and improper seperation depending on the number of theoretical seperation stages.

in the OP scenario TLC would only serve as an analytic tool, even column chromatography couldnt really yield a lot of DMT doses

youd be seperating by molecular weight if the different compounds had no intrinsic dipoles. i used to hate chromatography since its such a bitch ass compromising bullshit way of seperation... wait theyre all based on equilibrium

I started a thread on /spooky/ asking for any evidence of the paranormal or supernatural.

Instead all I got was a bunch of personal attack and people babbling nonsense and presenting it as truth. Then when shown they are incorrect with verifiable data rather than pseudoscience they resort to personal attacks again. They and pretty much all other magical thinkers take any sort of challenge to their beliefs as a personal attack.

I was at a party a few months back and some girl was talking about how she went to some yoga guy who does "laying on of hands". Which involves doing yoga while a dude puts his hands on your body and makes weird noises. Supposedly doing this achieves any number of effects from healing wounds, curing depression and other supposed boons.
not arguing the therapeutic effects of yoga just the laying on of hands part
I tried to understand what she was explaining to me by asking questions. Like asking her what was actually happening because it made 0 sense to me. Instead she started insulting me for being closed minded and shit.

Also in real life I live in the US south. Where people who think the world is 6000 years old is the norm.

Needless to say I deal with people who use magical thinking on a regular basis.
They are 100% willing to reap the benefits of science and the technology that comes with it until it conflicts with some myth or story about ghosts or some shit some one told them. Then all reason and logic go out the window.

Why do so many people especially in the us reject verifiable facts over what feels good? I went to the same public schools as them, I was also raised in a religious household (jewish, although I'm no longer religious). The only difference is that I chose the rational answer.

I agree, I just tend to shy away from the word. What happens all the time is the scientific community accepts something in a consensus, only to have that consensus overturned or it falls to more complete models. As you said, just try to keep a healthy dose of skepticism of everything since we are so far away from total understanding of anything, especially in the realm of physiology.

She was probably just saying that because she wanted you to be sceptical and then invite her to demonstrate or whatever out of "curiosity" and it would all quickly escalate into sex.

Didn't read the thread so don't know if anyone has already mentioned this, but you should look into something called 'English Prime.'

Basically it takes the concept of the Sapir-Whorf hypothesis (that language creates mental state, that ideas possible to be expressed within a language are the borders of the space in which speakers of that language can have ideas at all) and uses it to attempt to fix English by making it more explicitly scientific.

For example, it removes almost all constructions of 'to be' including 'is' and 'are.' Nothing is good, or bad, or blue, or fast, but can seem, or appear, or correlate to those properties. It basically forces people to remove the unscientific and unprovable but completely common habit of claiming things 'are' things, reducing it to the simple truth; that they seem to be things, and deliberately denying the power to speculate beyond to 'the thing in itself.'

Dear /chem/,

wikipedia cites that "Naltrexone can be described as a substituted oxymorphone – here the tertiary amine methyl-substituent is replaced with methylcyclopropane. Naltrexone is the N-cyclopropylmethyl derivative of oxymorphone."

Is it possible to revert naltrexone back to oxymorphone? If so, how?

My very limited understanding of organic chemistry leads me to believe that naltrexone could, in proper solution and (probably) with the addition of heat, be broken into oxymorphone and cyclopropylmethylbromide. (pic related)

Any input regarding said (hypothetical) reaction will be greatly appreciated!

Would it be possible to turn the cyclopropane into a terminal alkene using aluminum or something? I know cyclopropane's are very unstable.

And then would it possible to attach a carbon to the terminal alkene? You could attach a phenyl or something and make n-phenylpropyl.

Basically to sum up what I'm saying, instead of trying to remove the cyclopropylmethyl group outright, would it be possible to turn it into a 4 carbon chain, the last C=C being a double bond? And then using the reactivity of said double bond to attach something? You'd be able to make a pretty potent agonist that way.

I want to reduce 3,4,5-trimethoxy-beta-nitrostyrene to the amine. What will do this? I've found so much worthless and bullshit information. It seems the main options are:

  1. Zn/HCl or Fe/HCl. I don't know if this goes from the nitrostyrene to the amine or if I need to use NaBH4 to first reduce the double bond. Also, some people say the yields are good and others say the yields are shit.

2. LAH. Not an option.

3. SnCl2 to reduce the nitrostyrene to an oxime and then Zn to reduce the oxime to the amine. I've never found proof of anyone doing this reaction on nitrostyrenes. SnCl2 is good for reducing nitropropenes but who knows if that applies to nitrostyrenes.

4. Al/Hg. Literally toxic. I haven't found any reports of people using the less toxic Al/Ga or Al/Cu amalgam. I also get conflicting information saying Al/Hg reduces directly to the amine, yet others are saying NaBH4 must be used to first reduce the double bond and then the Al/Hg reaction can be run to reduce the nitro group to an amine -- which is it?

Any input would be appreciated, especially from people who have actually run these reactions on this particular substrate.

Are you planning on making larger quantities? if not, just go with al/hg. use your common sense and everything will be fine. solubility of mercury salts in organic solvents is negligible. when you worry about the organomercury compounds, just give your product (salt) a proper wash with organic solvents and acetone and you are golden

pushing it through a pad of celite or silica would help but honestly there isnt any reason to go with mg or tin
ochem portal has a page dedicated to conjugated nitro reductions...

Zn/HCl is the method of choice for terminal nitrostyrenes, but it fails for nitropropenes. Fe/HCl gives carbonyl compounds which you don't want. Make sure your zinc is good.
