Applications: Synthetic chrysophanol AS-G, chromogenic group of ice dye
3,3´-Dimethylbenzidine is mainly used to synthesize chrysophanol AS-G. CAS:119-93-7,And also used as chromogenic group of ice dyes, intermediate of azo dyes and resin curing agent. Used in dyestuff industry, spectrophotometric determination of gold, cerium and free chlorine as analytical reagent, adsorptive indicator and redox indicator. Nitrate, manganese, nitrite, chromium salt, copper salt, cobalt, mercury and cyanide ion in air were determined. The analytical standard is a sensitive colorimetric photosensitive method for the determination of gold and free chlorine.
3,3´-Dimethylbenzidine is also named as 3,3'-dimethyl-[1,1'-biphenyl]-4,4'-diamine(o-tolidine);4-(4-amino-3methylphenyl)-2methylaniline;dihydrofluoride and used as analytical reagent, adsorbent indicator and redox agent.The appearance is white to reddish crystal powder.
3,3´-Dimethylbenzidine that the UCHEM have a large inventory and price advantage.
