Acetanilide is primarily used as an intermediate in the synthesis of pharmaceuticals and dyes. In the pharmaceutical industry, it serves as a precursor for the production of paracetamol (acetaminophen), a widely used analgesic and antipyretic. Additionally, it is employed in the manufacture of sulfa drugs, which are essential antibiotics for treating bacterial infections. In the dye industry, acetanilide is utilized to produce various azo dyes, which are important for coloring textiles, leather, and paper. Its role as a stabilizer in hydrogen peroxide and cellulose ester varnishes further highlights its versatility in industrial applications.
