Description

Phosphorus Trichloride is a vital inorganic chemical intermediate essential for synthesizing a wide range of organophosphorus compounds. Its high reactivity makes it a cornerstone in the production of agrochemicals, pharmaceuticals, and flame retardants. This compound is a critical raw material for manufacturers in the chemical, agricultural, and specialty materials sectors seeking reliable, high-purity intermediates for their processes.

Application

• Agrochemical Synthesis: Primary intermediate for manufacturing organophosphorus insecticides, herbicides, and plant growth regulators.
• Pharmaceutical Intermediates: Key reagent in the synthesis of pharmaceutical ingredients and fine chemicals.
• Flame Retardant Production: Used in the manufacture of phosphate-based flame retardants for plastics and textiles.
• Plasticizer and Stabilizer Precursor: Serves as a starting material for producing phosphite and phosphate-based plasticizers and stabilizers for PVC and other polymers.
• Chemical Synthesis: Versatile chlorinating and phosphorylating agent in organic synthesis for laboratories and industrial scale production.
• Surfactant and Lubricant Additive Manufacturing: Used to produce phosphorus-containing additives that enhance the properties of lubricants and surfactants.

Quality Control

Our Phosphorus Trichloride is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay and impurity profile analysis, to meet exacting customer and industry specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as water, strong bases, and alcohols. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and decomposition. Recommended storage temperature is 15-25°C.
