Applications
UsesThiazole Yellow G is a triazene dye and acid-base indicator.
UsesDyeing cotton, viscose rayon, natural silk; as biological stain; as an analytical reagent, most often for the determination of Mg; as pH indicator, yellow 11.0 to red 13.0; as fluorescent dye for microscopy.
General DescriptionThiazole Yellow G is a pH sensitive chromoionophore.
Preparation methods
Preparation2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid diazo, and the 2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acidcoupling. In some closely related to the grade of the dyes, as one or two to a generation of 2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acidC.I.Direct Yellow 59 (C.I. 49000) instead. For example, Oxydiamine Yellow TZM structure is the 2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acidand C.I.Direct Yellow 59matches generated.
