Trihexyl phosphate(CAS: 2528-39-4)

Trihexyl phosphate (CAS: 2528-39-4) is a colorless to light yellow liquid with a molecular weight of approximately 321.45 g/mol. It has a low volatility and is slightly soluble in water but miscible with most organic solvents. Chemically, it is relatively stable but can react with strong bases and oxidizing agents. It is commonly used as a plasticizer and flame retardant.

Trihexyl phosphate (CAS: 2528-39-4) is typically synthesized by esterification of phosphate with hexanol in the presence of sulfuric acid as a catalyst. The reaction involves the conversion of hexanol to hexyl phosphate, which is then further esterified to form the trihexyl phosphate. The yield is around 85-95%, with high selectivity to the desired product.

Trihexyl phosphate (CAS: 2528-39-4) is widely used in the pharmaceutical industry as a plasticizer and stabilizer, in the polymer industry as a plasticizer and flame retardant, in the semiconductor industry as an antistatic agent, and in the sensor industry as a component in some sensor formulations.

When handling Trihexyl phosphate (CAS: 2528-39-4), always use personal protective equipment (PPE) such as gloves, goggles, and protective clothing. Store it in a cool, well-ventilated area, away from strong oxidizers and acids. Use a fume hood for any handling operations to avoid inhalation of vapors. In case of spill, neutralize with an alkali and dispose of according to local regulations. Always refer to the safety data sheet (SDS) for detailed safety information.
