Product Data Sheet
Direct Black 38
Catalog No. A44622
Direct Black 38 is a benzidine-based azo dye primarily utilized in textile dyeing applications. Its primary mechanism involves the degradation of azo bonds by microbial enzymes, particularly Enterococcus gallinarum azoreductase, leading to the release of benzidine and 4-aminobiphenyl. This compound is significant for studies in environmental toxicology, wastewater treatment, and carcinogenicity, although it is essential to note that its metabolite benzidine is classified as a human carcinogen.
