General Description
1-[[4-[[4-[(2-hydroxy-1-naphthyl)azo]-2,5-dimethylphenyl]phenylmethyl]-2-methylphenyl]azo]-2-naphthol, also known as Sudan I, is a synthetic azo dye that is commonly used to color industrial products such as oils, waxes, and polishes. However, it is also known to be a potential carcinogen, and its use in food products is prohibited in many countries. Ingestion of Sudan I has been linked to liver and bladder cancer, and it has been the focus of food safety regulations and recalls due to its potential health risks. Due to its carcinogenic properties, the use of Sudan I has become heavily restricted and regulated, with efforts to find alternative colorants for industrial and consumer products.
