Tomczyk, Danuta published the artcileApplication of column chromatography in the analysis of intermediates and dyes. III. Photometric determination of dehydrothio-p-toluidine in crude product, Related Products of thiazole, the publication is Chemia Analityczna (Warsaw, Poland) (1974), 19(6), 1247-51, database is CAplus.
Crude dehydrothio-p-toluidine (I) [92-36-4] dissolved in EtOH was separated by chromatog. on a cellulose powder column with EtOH as the mobile phase followed by photometric determination of collected I at 460 nm after its reaction with p-Me2NC6H4CHO. Standard deviation was 0.75% for the crude product containing 65% I and time of determination was 2.5 hr.
Chemia Analityczna (Warsaw, Poland) published new progress about 92-36-4. 92-36-4 belongs to thiazole, auxiliary class Organic Pigment, name is 2-(4-Aminophenyl)-6-methylbenzothiazole, and the molecular formula is C4H8F3NO, Related Products of thiazole.
