Thiocyanate testing
WebThe cobalt thiocyanate test has been shown to react with tertiary protonated amines. When cobalt thiocyanate interacts with cocaine or fentanyl a blue color change occurs. Cobalt thiocyanate has also been demonstrated, through our preliminary testing, to give a false-positive blue color change for diphenhydramine, an anti-histamine that is not ... WebAn interesting analogue of the cobalt thiocyanate test is described by Travnikoff, who has developed a complexing reagent composed of an aqueous phase containing a solution of copper sulphate and potassium thiocyanate and an organic phase consisting of chloroform [ 64] ; addition of cocaine causes the chloroform layer to turn brown. Cocaine ...
