Product name: Tris(2-Chloroethyl) Phosphate
English alias: TCEP; Tris(β-chloroethyl) phosphate; Phosphoric acid tris(2-chloroethyl) ester
CAS: 115-96-8
Molecular formula:C₆H₁₂Cl₃O₄P
Appearance:Light yellow oily liquid
Package: 25 kg/bag
Tris(2-chloroethyl) Phosphate (TCEP) is a chlorinated organophosphate compound with the molecular formula C₆H₁₂Cl₃O₄P. It is a versatile flame retardant and plasticizer known for its excellent flame-retardant efficiency and compatibility with various polymers. TCEP appears as a colorless to pale yellow transparent liquid with a mild odor. It exhibits low viscosity, good thermal stability, and resistance to hydrolysis. This compound is widely used in polyurethane foams, unsaturated polyesters, and other polymer systems where effective flame retardancy is required. However, due to environmental and health concerns, its use is subject to regulations in various regions.

TCEP is classified as a substance of very high concern (SVHC) under REACH due to its carcinogenic and reproductive toxicity properties. It may cause damage to organs through prolonged or repeated exposure. Appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection must be worn during handling. Avoid inhalation of vapors and direct contact with skin and eyes. Use only in well-ventilated areas or with local exhaust ventilation. TCEP is persistent in the environment and may cause long-term adverse effects.
