Description

m-Nonylphenol CAS NO 139-84-4 is a branched-chain alkylphenol, specifically an isomer of nonylphenol where the nonyl group is attached at the meta position of the phenol ring. This compound serves as a critical intermediate and functional additive in the synthesis of various high-performance industrial chemicals. It is primarily required by manufacturers in the polymer, surfactant, and lubricant industries for its role in producing nonionic surfactants, phenolic resins, and antioxidant stabilizers.

Application

• Surfactant Intermediate: A key raw material for the production of nonylphenol ethoxylates (NPEs), which are widely used nonionic surfactants.
• Polymer Industry: Acts as a monomer and chain modifier in the synthesis of phenolic resins and epoxy resin hardeners.
• Lubricant & Fuel Additive: Employed as a precursor for antioxidants and detergency additives in lubricating oils and gasoline.
• Chemical Intermediate: Used in the manufacture of phosphite antioxidants, plasticizers, and other specialty chemicals.
• Agricultural Chemicals: Serves as an intermediate in the synthesis of certain pesticides and emulsifiers for agrochemical formulations.
• Rubber Industry: Functions as an antioxidant and stabilizer in the production of synthetic rubber.
