    Abstract

    A number of reports on the use of thin-layer chromatography (TLC) in the analysis of street drugs have appeared [1–3]. Colors with various visualization agents applied in sequence are used for identification in conjunction with Rf values, spot tests [4], and crystal tests [5]. This paper reports the use of a rapid TLC screening procedure that utilizes a single developing solvent and a single visualization reagent, N,2,6-trichloro-p-benzoquinone imine (TCBI), for the preliminary identification of the drugs of abuse. In addition, other TLC developing solvents are outlined that can be used for further confirmation.
