  • Applications

    N-phenyl-2-naphthylamine (CAS 83777-95-1) is used primarily as an amine antioxidant for natural and synthetic rubbers to suppress heat-, oxygen-, and flex-induced degradation and extend the service life of tires, conveyor belts, hoses, and seals; as a stabilizer/antidegradant in plastics, coatings, and epoxy resins; as an antioxidant additive in lubricating oils, greases, and certain fuels to reduce gum formation and performance loss; as an intermediate for azo dyes and high-performance pigments; and as a reference additive in materials research on radical-scavenging protection, with modern use often restricted or replaced by lower-hazard alternatives due to safety and regulatory concerns.
