Sudan I (Solvent Yellow 14) is a diazo-conjugate red dye commonly used as an additive in products such as oils, solvents, and polishes. This monoazo dye, with the chemical formula 1-phenylazo-2-naphthol, is known for inhibiting the growth of bacterial strains *Clostridium perfringens* and *L. rhamnosus*. It is classified as a potential mutagen and carcinogen for humans, capable of inducing genotoxic effects in HepG2 cells and increasing mutagenic and clastogenic effects in MCL-5 cell lines compared to AHH-1 cell lines. It also yields positive results in *Salmonella Typhimurium* mutagenicity tests with S9 activation.
