  • Applications

    m-Cresol (CAS 108-39-4) is an aromatic phenolic compound with broad industrial utility, serving as a key intermediate for producing phenol-formaldehyde, epoxy and polycarbonate resins, forming the backbone for the synthesis of the antioxidant BHT and synthetic vitamin E, acting as a specialized solvent in printing inks, circuit-board cleaners and electronic adhesives, providing strong bactericidal activity that makes it valuable in disinfectant formulations, wood preservatives and veterinary medicines; in agrochemicals it is converted into herbicides and pesticides, while in the dye and fragrance sectors it is a precursor for certain azo dyes, smoke-flavor enhancers and cosmetic aroma components; additionally, m-cresol is employed as a polymerization inhibitor, fuel stabilizer, lubricant additive, and viscosity modifier in industrial ink-jet inks.
