if i wanted to start a small business where i test people's drugs for fent/pcp/meth/clam or whatever, what sort of reagents would i need to buy? I realize this is sort of an open ended question, i'm just sort of looking for general suggestions for pretty much any drug testing reagent that tests for something. there's pretty much nowhere that you can safely get your drugs tested around where i live & i really want to do what i can to help. i feel like i could save some lives with this.

especially looking for something that can detect if my jenk's been cut with dog pills

i don't know how above board this business will be, but i'm in a pretty lenient part of america drug wise so i doubt i'd get in much trouble for people sending me small samples for chemical analysis. also is there any reagent/combination of reagents i can use to test for different benzodiazepines? from my initial googling it doesn't seem very easy but i would really like to be able to tell people if their xans were cut with clam or flam etc

I heard that if an elephant’s metabolism were any faster then it would burn from the inside out because it’s body is way too big to effectively dissipate heat. So it has a very slow metabolism. Is this true?

concerning the synthesis
this is some pretty whack shit. you can even synth superphane but this would be way too much strain on the sp2 carbons of the benzene.

theoretically speaking its an 5-amino anhydride derivative of isophthalic acid, my best guess is that its an exercise aimed at the nomenclature or bicyclocompounds or rather heterocycles.

could you double check if you got that structure right?

Sup /chem/,

There is a fundamental gap in my understanding of the universe. When we look out into the sky and see the sun and stars, measure the Earth orbiting the sun, or see a volcano, it is commonly accepted that eventually, all of these processes will run out of energy and cease to do their thing. However every atom in the universe has positive and negative charges, with the negatively charged particles constantly in motion (and i guess the positive ones too if we count vibration or whatever). How do subatomic particles get a charge in the first place? Will it ever wear off? What makes electrons move? Will an electron ever stop moving and become neutrally charged? Can we apply this seemingly infinite source of subatomic energy to the macro scale to prevent a big freeze or one day generate limitless energy?

Does anyone please know of a general way to determine if there's any local max and min *within a set range of X-coordinates*?

As we can see, there's a local max somwhere around -1 and a local min somwhere around 3 and none whatsoever in the range 1-2.

But how do I prove that there's no local max nor min in that range?

I'm looking for *local* max/min in trig-functions. I know that if the x-range is long enough, there will be *many* local max/min.

For instance this function has local max/min all over the place and repeats itself every 3600 x:

f(x) = sin x(sin (x/10))

I know there's a local max between x(1500) and x(1530). But how do I prove it by doing a f'(x) for only that range?

I think it still works the same way. Take derivative. Set equal to 0. Solve within your range. That's a lot of trig functions to fuckin deal with. Here's wolfram alpha's solutions:


Solutions are at the bottom. Hit the 'exact solutions' to see what kinda algebra is needed for that function. So obviously the way to do this is numerically. Look at the original function

Then look at the approximate solutions in the last page. You can see that the local maximum for that range is at:
For which the function returns: 0.987810970335936684937

Or, in one easy step: https://www.wolframalpha.com/input/?i=maximum+sin(x)(sin(x%2F10)),+1500%3Cx%3C1530

Maybe that's cheating, but fuck trying to analytically solve that.

the fact that youve posted that is further evidence of the genius of the idea to establish a /shill board. naw just kidding.

concerning the analytic component of the question, im kinda ashamed it took me this long to think of, you could take the derivative via product rule (not sure if another approach would deliver something more moldable) and then reason examine the zero points of the derivative and second derivative.

im a bit confused as to what the actual function is, should it - as mentioned before - be y= sin(x) sin(1/10), the derivative itself will be a sum of two periodic products, meaning youd have to evaluate cases where either both terms are zero or one term is the negative of the other. depending on the range the answer should be given in multiples of some fraction of pi (kirt, tex support when)

during my analytics classes giving a numeric answer was a telltale sign of misunderstanding the task

And should your task be to prove that the function has a local min/max on a given closed range you could simply show that the function is continous (as a composition of continous functions) and then a local min/max has to exist.

Naltrexone -> Oxymorphone? by Hamilton Beggleshit - Thu, 17 Mar 2016 18:16:02 EST ID:GksK9UMc No.77752 Ignore Report Reply Quick Reply

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.

Cyclopropanes are very unstable but the one pictured with a stabilized alkane group is not. This group shown with an R-cyclopropane is relatively stable.
Carbon-carbon chemistry is very hard. Even harder to do selectively.

Hey guys.

So recently I've been interested in irreversible opiates.

A couple decades ago some scientists were able to do this by adding a hydrazine at the 6 ketone of oxymorphone, as well as at naltrexone/naloxone, making oxymorphazone and the corresponding nalts.

When tested, these hydrazines lasted extremely long, and blocked any further effect of opiates in animals. As well, radioactive versions of the drugs cold simply not be washed away from tissue expressing opiate receptors. Meaning these drugs were staying bound to the receptor.

Originally it was thought that oxymorphazone itself was doing the irreversible binding, but it was later determined that the oxymorphazone was joining up with itself spontaneously in solution, creating a dimer of sorts, oxymorphazine.


There's no wiki on Oxymorphazine, but here's something similar: https://en.wikipedia.org/wiki/Oxymorphone-3-methoxynaltrexonazine

It's just two oxymorphones joined by a hydrazine at the 6 position of each.

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.
