CAS 78-40-0
Product Overview
Triethyl phosphate, commonly abbreviated as TEP, has a CAS number of 78-40-0, molecular formula C₆H₁₅O₄P and molecular weight of 182.15. Classified as an organic phosphate ester compound, it is a clear, colorless oily liquid soluble in water and most organic solvents including alcohols, ethers and benzene. It delivers good compatibility, low volatility, plasticizing and flame-retardant properties, and is widely adopted in fine chemical synthesis, polymer processing, pesticide and coating industries.
Triethyl phosphate comes with versatile functional properties preferred by chemical manufacturers and formulators. As an efficient plasticizer, it can enhance the flexibility and processability of polymer materials without significantly compromising material strength. It also functions as a non-halogen flame retardant for cellulose, phenolic resin and other polymer systems to restrain combustion and reduce smoke emission. In organic synthesis facilities, TEP serves as a reaction solvent and catalyst carrier for various condensation and alkylation reactions. It is also added into pesticides and coatings to improve permeability and film-forming performance.
Our triethyl phosphate is offered in high-purity industrial grade. Every batch goes through rigorous laboratory quality testing, and we can provide COA, SDS and other export documents upon request. We maintain stable raw material supplies and flexible packaging options ranging from small sample drums to bulk ISO tanks. Our QC system strictly monitors indicators such as moisture, acidity and purity to minimize batch variations, helping customers stabilize production and lower raw material costs.
Safety protocols must be observed during handling. Operators should wear protective gloves and eye protection to prevent direct skin or eye contact. TEP should be stored in sealed containers within a cool, dry and ventilated warehouse, separated from strong oxidizing agents and strong bases that may cause hydrolysis and decomposition. With extensive export experience, we can arrange suitable shipping solutions for different destination countries. Whether you need trial samples or large bulk orders, our team can recommend appropriate product solutions based on your practical applications.
