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
