Abstract |
3-Methyl-2-benzothiazolone hydrazone is shown to be a powerful and versatile electrophilic reagent which can be used for the spectral detection and determination of strongly nucleophilic molecules containing a carbon atom of high electron density. The determination of approximately 50 azo dyes and a smaller group of stilbene and Schiff base derivatives by a new procedure for these compounds is described. 4-Amino-, 4-alkylamino, and 4-dialkylamino derivatives of azobenzene can be readily analyzed. The determination of N,N-dialkyl-4-aminoazobenzene was thoroughly investigated. (Author) |
