1. What is in the pipette and in the flask?
2. What is it used for?
3. What are the limitations to this assay?

Our Geek of the Week answered:
This is cobalt thoicyanate. It is a presumptive test for cocaine. It does cross react with other substances, and we would add hydrochloric acid to test cocaine base.
[BLOGGER’S NOTE: Here is some more information:

“The pipette is adding cobalt thiocyanate solution (pink) to a sample of cocaine (white) to produce the blue precipitate that is the [presumptive] positive result of this test for cocaine… The conical flask at upper left contains cobalt thiocyanate solution, which needs to be acidified to ensure detection of some forms of cocaine.”
This is also referred to as the “Scott Test.” There are a lot of substances that can cause false positive when this reagent is used. This includes, but is not limited to: (1) antihistamines that include Diphenhydramine as a component such as Nytol, Unisom (though some Unisom products contain doxylamine instead), Tylenol PM, Midol PM and Advil PM and (2) any compound that has lidocaine in it. There are other substances that will also respond as a false positive. Therefore, at most, it is a screening assay.
There are two great Honorable Mentions (Remember the winner is the first correct and complete answer. So, that means our Honorable Mention folks were just a little behind our Forensic Science Geek of the Week Winner.):
David M. Benjamin, Ph.D., Clinical Pharmacologist and Forensic Toxicologist, wrote: “This is a cobalt thiocyanate screening test for cocaine. Cobalt thicyanate is pink, and the crystals in the reaction vessel are cocaine powder. It’s use is for the presumptive or preliminary qualitative analysis of cocaine HCl and, maybe cocaine base, which may require the addition of HCl to convert the cocaine base to HCl (hydrochloride) to obtain the “blue color” indicating the possible presence of cocaine. It’s limitations are that it is a screening test and requires confirmation by either IR spectroscopy or GC/MS, and that both diphenhydramine (Benadryl), an antihistamine, and lidocaine, (Xylocaine), a local anesthetic, give “false positive” blue colors which can be misinterpreted as an indication of the presence of cocaine.”
Mehul B. Anjaria wrote “Looks like the cobalt thiocyanate test for cocaine. This is a simple color test that is presumptive in nature. It therefore, is in no way is a chemical confirmation that the substance contains cocaine. The reagent is added to suspected cocaine. Cocaine hydrochloride will then turn bright blue (with crack or cocaine base producing only a dull blue). The subsequent addition of hydrochloric acid will change the color back to pink. Good test for the field and to guide the rest of the analytical process toward a suspected family of drugs; however, it is solely a presumptive test as false positives will occur.”
