A SIMPLE COLORIMETRIC DETECTOR OF SYMMETRIC 2-(DIALKYLAMINO)ETHANETHIOLS AS PRECURSORS OF V-TYPE NERVE AGENTS

A colorimetric detector tube of 2-(dialkylamino)ethanethiols as precursors of V-type nerve agents and their hydrolytic products was designed. The detector is based on a reaction of 2-(dialkylamino)ethanethiols with a chromogenic reagent 4-chloro-7-nitrobenzofurazan (NBD-Cl) in alkaline medium leadin...
