SMILES: O=S(C1=C(/N=N/C2=CC=C(C3=CC=C(/N=N/C4=CC=C(N)C=C4N)C=C3)C=C2)C(N)=C5C(O)=C(/N=N/C6=CC=CC=C6)C(S(=O)(O[Na])=O)=CC5=C1)(O[Na])=O
Biological Activity: Direct Black 38 (Chlorazol Black E) is a benzidine-based azo dye, a substrate of Enterococcus gallinarum, and is mainly used for textile dyeing. Direct Black 38 is biodegradable after being reduced by microbial enzymes (such as Enterococcus gallinarum azoreductase), breaking the azo bonds and releasing benzidine and 4-aminobiphenyl. Direct Black 38 can be used in environmental toxicology, wastewater treatment and carcinogenicity studies, but its metabolite benzidine is listed as a human carcinogen[1].
