Ghosh PB, Whitehouse MW (1968) 7-Chloro-4-nitrobenzo-2-oxa-1,3-diazole A new fluoro-genic reagent for amino acids and other amines. Biochem J 108 155-156... [Pg.57]

NBD-CI, 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole MSTFA, N-methyl-N-(trimethylsilyl)trifluoroacetamide BSA, N, O-bis(trimethylsily-l)acetamide MTBSTFA, N-methyl-N-(tetr.-butyldimethylsily)trifluoroacetamide BSTFA, N,0-bis(trimethylsilyl)trifluoroacetamide HFB, heptafluorobutyric acid SFE, supercritical-fluid extraction. [Pg.1113]

Specific procedures for the detection of this group of drugs have been described [67,69,70]. These methods are based on thin-layer chromatography (TLC) in combination with fluorescence induction of the NBD-derivatives (7-chloro-4-nitrobenzo 2 oxa 1,3 diazole) of the drugs with cystein, combined with a rapid and selective extraction procedure, based on a specific complex formation of the drugs with mercury ions. The sample cleanup with the mercurated affinity column... [Pg.471]
