Description

Triethyl Phosphate is a versatile organophosphorus compound widely used as a solvent, chemical intermediate, and flame retardant. Its unique properties make it a critical component in the synthesis of pesticides, pharmaceuticals, and high-performance polymers. This product is essential for manufacturers in the agrochemical, pharmaceutical, and plastics industries seeking a reliable and high-purity chemical reagent.

Application

• Chemical Intermediate: A key raw material for the synthesis of organophosphate pesticides, herbicides, and insecticides.
• Pharmaceutical Synthesis: Used as a solvent and reactant in the production of various active pharmaceutical ingredients (APIs).
• Flame Retardant & Plasticizer: Imparts flame-retardant properties to unsaturated polyester resins, cellulose acetate, and other polymers.
• Catalyst & Stabilizer: Acts as a catalyst in transesterification reactions and a stabilizer for peroxides and chlorinated hydrocarbons.
• Solvent & Extractant: Employed as a solvent for cellulose derivatives, resins, and as an extractant for rare earth metals and other separations.
• Gasoline & Lubricant Additive: Used as an anti-wear agent and lead scavenger in aviation fuels and lubricating oils.

Quality Control

Our Triethyl Phosphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets the highest standards for purity and consistency. A Certificate of Analysis (COA) detailing specific results for identity, assay, and impurity profiles is provided with each shipment to guarantee reliable performance in your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its hygroscopic nature, containers should be kept tightly sealed to prevent moisture absorption. Recommended storage temperature is 15-25°C.
