Detection and identification of diluents in common drugs samples is frequent and challenging task for forensic chemists. Appearance of new drugs or combination of new drugs and misuse/ abuse of drugs, used for medical purposes, not only has substantial and detrimental effect on the health and welfare of the people and also generates several serious sociological problems. The present work describes the detection and identification of uncommon diluent’s Chlorophenraminemaleate in narcotic materials by chemical colour tests, thin layer chromatographic and U. V. spectroscopy.
