In Vitro Sudan I is a monoazo dye with the chemical formula of 1-phenylazo-2-naphthol. Sudan I can cause tumors in the liver or urinary bladder in mammals and is a potential mutagen and carcinogen for humans. Sudan I induces genotoxic effect in HepG2 cells and increases mutagenic and clastogenic effects in the MCL-5 cell lines compared to the AHH-1 cell line. In addition, Sudan I also gives positive results in Salmonella Typhimurium mutagenicity tests with S9 activation, a post-mitochondrial fraction prepared from the livers of rats[1].
