3,3'-Dichlorobenzidine and its dihydrochloride.
Report on carcinogens : carcinogen profiles, 12, 141-143 (2011-08-19)
Lei Wang et al.
Toxicology, 207(3), 411-418 (2005-01-25)
DCB, 3,3'-dichlorobenzidine, is used primarily as an intermediate in the manufacture of diarylide yellow or azo red pigments for printing ink, textile, paint, and plastics. It is also used in tattoo inks. In this article, we investigate light-induced toxicity of
Francis P Donaldson et al.
Environmental toxicology and chemistry, 24(5), 1022-1028 (2005-08-23)
Aromatic amines, such as benzidine and 3,3'-dichlorobenzidine (DCB), are part of the dyes and pigments manufacturing process. The prolonged use of these carcinogenic chemicals in the past generation has introduced a significant amount of contamination to the environment. Their persistency

Toxicology and industrial health, 18(4), 191-199 (2003-09-17)
3,3'-dichlorobenzidine (DCB) can be metabolically N-acetylated and/or N-oxidized, and can form hemoglobin adducts. Gas chromatography/mass spectrometry-selected ion monitoring detection mode (GC/MS-SIM) could be a good analytical method to detect them. 4-Aminobiphenyl and phenanthrene-d10 were used as internal standards, and standard
Takeshi Ohe et al.
Mutation research, 655(1-2), 28-35 (2008-07-19)
3,3'-Dichlorobenzidine (DCB), which has been assigned as a possible carcinogen to humans (Group 2B) by IARC, is produced as a raw material in the manufacture of polymers and dye intermediates. In our previous paper, we identified DCB as an indirect-acting
