Imagine you have a big list of cities and wanted to concisely get an idea of what the weather is like over there.
If conciseness and speed wasn't a problem, you could look at a graph like that for each city, but that's not feasible.

So what metrics would you need to accurately capture the climate of that area? Less is better, so all I can think of is: average lowest temp, average highest temp.
Any other ideas?

a search tells me that PG USP/EP has a shelf life of two years when stored below 40°C (104°F) in closed containers away from sources of ultraviolet (UV) light.

I just proposed this on /psy/ so let's see what you people think.

I do have an add-on, though. L-Tyrosine can be decarboxylated to Tyramine so you don't have to get a shitload of cheese to extract. From there, you can just brominate it selectively in basic conditions to brominate the carbons meta to the hydroxide. A simple LG > Hydroxide reaction later, you'll have 2,3,4 tri-hydroxyl(aminoethyl)benzene.

One simple reflux with 4eq of Methyliodide should yield mescaline in 95%+ yields. What do you think, /chem/?

If Ti has the follow electron config as a base config: (where ^ represents an e-)

^^ ^ ^
4s 3d 3d 3d 3d 3d

would it hybridise to the following (to accommodate (Cl-)4)?

sp3d sp3d sp3d sp3d sp3d

leaving it with a final config of (with bonded (Cl-)4):
^ ^ ^ ^ ^ ^ ^ ^
sp3d sp3d sp3d sp3d sp3d

thereby classifying it as a lewis acid because it can accept a lone pair?

hey man not sure im following you exactly, but it would be much easier to think of this in terms of CFT/ligand field model, as in 4 M-L bonding interactions lying lower in energy than the metal based d-orbitals (e and t2 sets) which have an occupancy of 4. Electronically speaking TiCl4 has low-lying MO's, of primarly Ti character, so yeah it is fairly electrophilic and a decent lewis acid. evidenced in that it happily forms adducts with donor solvents such as THF

in a context of conducting a synthesis, does it matter whether a reagent is in a form of a salt or not? can you even make such a general statement?

i'm asking because im interested in the chemistry behind converting codeine phosphate to morphine. does it matter whether someone uses codeine phosphate or codeine freebase?

Depends on the solvent your going to carry out your reaction in. In most cases i can think of the freebase is required. Careful, codeine is easily destroyed by strong acids and bases. Hell, even heat and a little too much ammonia will do it. Also too much water and it will stay in the aqueous layer. Work as small as you can because 9 times of of 10 you will have failures.

codeine 300g/mol
codeine phos 397g/mol
ammonia 17g/mol
sodium carbonate 106g/mol

0.001mol 1mmol codeine phosphate = 397mg
add 1mmol ammonia = 17mg or 170mg 10% ammonia
or add 0.5mmol carbonate because there are 2 sodiums = 53mg
and you should be left with 300mg codeine

In reality you will likely need a little more base in many cases, but it gives you a general idea how much to start with.

Thanks for the pointers!

This is not really serious enough to warrant that. This is more something productive to do for fun instead of blunting my brain with those animoos and games. Checked out Zumdahl though, seems just right for my way of learning.

Transmitting antennas are designed to be radiators. An anti-radiation "antenna" is a dummy load which is useful when you want to test a transmitter without radiating a signal.

Coffee Filters are best, fine scientific filters tend to filter rather slowly. If you are working with Ibuprofen, you're better off decanting - it is heavy and highly insoluble even at room temperature, so it will form an adhesive block at the bottom of the container that won't fall out even when tilted at a strong angle. Paracetamol is a bit more awkward.

I've gone through this process to convert salts -> freebase by:
adding some salt drug to a lye solution then using hexane to pull the freebase and evaporate.
My question is: while this process seems to have to have worked with a 2C and with U-44770, can you think of any case where the NaOH will mess up the drug somehow? Or a case where the freebase won't dissolve in the Hexane?

2) Is acetone good enough for purifying most drugs? How are you even supposed to know the solubility of a lot of these new drugs like 4-methyl-pentedrone or 3-Fluorophenmetrazine? Acetone is used for MDMA and Ketamine purificaiton, so what stuff does it NOT work on?

Hi all,

I hope I'm asking this in the best spot & really hoping someone can assist me w/this......

So I'm getting ready to try ULDN for the 1st time, that is if I can get this figured out. So I thought I added my 50mg tab of naltrexone to 1 liter or 1000mls of water however I didn't look close enough at the bottle I'm using, duh I know. Anyhow instead of 1 liter the bottle I added everything into is 1.25L.
So I'm trying to figure out how many mcg's I have per ml. The recipe I followed has the dosages based on 1 ltr not 1.25 ltr. Considering this is touchy & the dose is based on mcg's I wanted to verify what I now have w/some folks that are way better in the chemistry & mixing department.
I would be very grateful for any info you may be able to provide. Anything you also may like to add about ULDN would also be greatly appreciated.

Thank you!

you might want to either get a volumetric flask, which might get expensive i dunno, or find a bottle with which you can very accurately measure a set volume. ideally it would be a bottle with a very thin neck, which would be filled to a certain level of the neck

if your solution is really mixed and the naltrexone is readily water soluble you could store it in several small containers while frozen. then youd simply have to take out a single container, thaw it and shake it before use while the others still remain frozen.

any idea how big one of your drops is? or how much one drop weighs?
LaDiDotty - Thu, 24 Nov 2016 14:24:51 EST xxe0PbAv No.78366 Reply

I don't have any fancy measuring bottles, can you suggest somewhere I could find one in expensively? The recipe I'm following is to mix 1 50mg tab into 1L but it makes a huge amount. I was thinking to see if I could cut a tab in half or even quarters, cut the water down accordingly but I'm afraid of possibly not cutting it perfectly in half or quarters each time. Your idea of storing in the freezer is great! I was afraid the solution would go bad before I'd ever get thru an entire liter. Even though the naltrexone tabs were easy enough to get I'd prefer not to waste them. I found it odd that w/each study or recipe I found nobody talked about properly storing the mixture or preserving it aside from putting the mix in an amber or cobalt glass bottle or storing in the fridge.
Do you think freezing the mixture would degrade it in any way? Do you know if the mixture is sensitive to light?
I did get a couple different syringes from the pharmacy, 1 I think is useless for dosing anyways, it's more of a child's medicine dropper, 5mls w/o small enough increments for dosing, maybe good for something else. The other syringe is 1ml, has .10 increments & even smaller. I just tried counting how many drops a full ml holds & came up w/30 almost 31 drops. One study & recipe I read said their 1ml dropper held a perfect 20 drops. Not sure what they're using but I tried several times & came to 30-31 each time.
With the recipe I'm following it says that what I should end up with is 50mcg per 1ml & .2 ml = 10mcg. Because I accidentally didn't see the bottle I'm using is a 1.25L instead of a 1 L my drops are slightly diluted. I found a couple other recipes but they're all relatively the same.
The naltrexone tabs I got dissolve very fast & completely in water. One recipe said not to shake the tab in the bottle, that made no sense to me since you want to make sure you have even doses. Another recipe said to shake it vigorously, I did the latter. When I dropped the tab in the water I just left it to dissolve while I ate dinner. When I came back it had totally dissolved on its own w/just an uber tiny amount of particulate floating around. I just shake it real well before each dose. When I draw the fluid into the syringe the water looks completely clear.
While I find it fascinating, I don't have a lot of experience w/chemistry or atleast the experience I do have involves health & beauty care items & there's rarely addition if any micro sized ingredients. Do you think I could find any of the items you suggested on EBay or Amazon? Or is there a better place to buy volumetric flasks, vials, etc?

Sorry for the long post. Thank you so much for all of your help, I really do appreciate it. I hope you have a nice Thanksgiving today!

id try ebay or amazon for chinese volumetric flasks. doesnt matter wether its a plastic one or one made from glass aslong as the mergin of error is tight enough. real men use glass, because theyre not afraid of suffering the pain of fucking up.

a volumetric flask should be cheaper than a really accurate scale. how accurate is yours?

i dont really see how using amber or colbalt glass bottles would help, those are normally used for light sensitive stuff but im not sure about naltrexone being light insensitive. my bet would be that it shouldnt be, since ive never heard of morphine or oxymorphone are. its not going to degrade when its frozen, but be sure to really give it a good shake after dethawing it. use plastic bottles for storing it frozen. ive seen quite a few phds fucking that up once in a while.

for measuring the final dose a syringe is good
the size of a drop also depends of the diameter of the opening so its not a suprise they found some other ratio. i have no idea about ultra low naltrexone, once read that it can reap lotsa benefits but i dont remember the dosage tl;dr cant get lantrexone anyways

i guess the particulate is some gunk like magnesium stearate or some other stuff they put in to make the pill super duper
no biggie, you have a nice one too
