Direct Black 38 free acid

Catalog No.: A44744
Azo Dye
Direct Black 38 free acid is a benzidine-based azo dye that serves as a substrate for Enterococcus gallinarum. It exhibits biodegradability through microbial enzymatic reduction, resulting in the cleavage of azo bonds and the release of benzidine and 4-aminobiphenyl. This compound is primarily utilized in environmental toxicology, wastewater treatment, and carcinogenicity research, although caution is warranted due to the classification of its metabolite, benzidine, as a human carcinogen.
