Cocaine Purity

I to am looking at an accurate way to test cocaine , i know there is a test kit but cant seem to find one abywhere , any ideas where i can look ?? Also where can i get hold of pure cocaine ???

 

I dont know if this company still exists but if it does send it to pharm chem.

 

PLEASE DONT BOTHER WITH TONGUE TESTING MANY DEALERS CUT THEIR CHARLIE WITH LIDOCAINE WHICH IS A TOPICAL ANAESTHETIC, STICK WITH THE HEAT.

 

use tlc ( thin layer chromatography) good way of estimating purity and good way to identify impurities

 

so far the most intilligent answer has been thin layer chromatography, other then that, and possibly more available is actually get litmus type testing kits or chems some are avail at http://www.eztest.com/shop/, they are european, but ship worldwide, and have testing kits avail for coke, mdma, ketamine, anphetimines and the related sub drugs as well

 

there are good "purifying cocaine hcl" teks out there that are pretty easy.

but for F&L, they didn't capture the amount of speed that they were doing in the movie...he was strung out on speed for a good portion of the book.

 

what is the best way to easily test in my house, and lose the least amount.

how much is the mimimum for the hot plate test to work? 0.5 or 0.3?
would suck to lose a whole gram.

 

If you're going to use melt point, you need either a melt point device, or at least (not near as good) a laser thermometor with your hot plate.
The more product you test the better, as it is the RANGE of the melt that must be observed (easier with larger amounts), to estimate purity-- unless you have pure cocaine, which you don't.

In any case, there's not much you can do about the presence of tropacocaine and other natural alkiloids present. Lidocaine ain't going nowhere either.

Dry some acetone, wash the product, and hope for the best.
I know what I'm talking about.

 

this got me thinking the other day. the other alkaloids in coca leaf.. How do they not make it into the cocaine?. the nicotine for one, does this componant of cocaine make it more addictive than it is.....

I was gonna ^ make a whole thread but eh' ..

 

melting point tests are measured in terms of spread, not target? 191 ± 3 would describe pure HCl but you may have fumate, it's used to avoid dogs. What you take may have had the salt cleaving and reattached a few time before you get it. Doesn't mean it's bad.

In the real world people use a shot glass full of fresh chlorine bleach, freshly broken seal, nothing more. Red, pink and orange discolouration means an amphetamine is present. If you get good you'll elarn to identify which synthetic x-caines are there too. Fast falling particles are hard (low level dealer) cuts, the salted coke takes a few seconds then snows down gently, floating particles are low level cuts although pure coke from a block leaves oil on top and some particles.

 

Use capillary tubes and a theil tube, minimal cost.

range is easier with small amounts and a magnifying glass, that's what capillary do. All lab equipment does the same by pressing the sample, you can't pass a lab class by using large amounts of any sample; you're increasing the temperature at a constant rate while observing, the smaller the sample the more accurate the observed range as the whole thing is the same temperature, less latency and temp gradient across the sample.

You can remove lidocaine from the cut, the last text to suggest otherwise was written in 1981, 30 years ago.
