Description : Triethyl phosphate CAS 78-40-0 is a premier halogen-free flame retardant and high purity fine chemicals catalyst used extensively in the production of ketene and as a versatile solvent for cellulose acetate. Phosphoric acid triethyl ester serves as a critical intermediate in the API intermediates market, where its use as an ethylating agent is increasingly managed through custom synthesis services to meet stringent CDMO growth requirements. TEP provides industry-specific purity of 98% for the plastics and resins industry, acting as a functional viscosity reducer and stabilizer that aligns with current global sourcing shifts toward sustainable and compliant chemical additives. As globally established Triethyl Phosphate (TEP) supplier, we ensure dependable supply, consistent quality, and complete regulatory documentation, including CoA and TDS across all grades. Beyond supply, we support partners through the entire product lifecycle from route scouting, process and formulation development, and analytical method development to scale-up, process optimisation, and pilot-to-commercial manufacturing. Our teams also assist with GMP-compliant quality assurance, regulatory documentation, and global supply chain and logistics coordination.
