Product Overview

• Phosphorus Trichloride is a highly reactive inorganic chlorinated phosphorus compound, appearing as a clear, colorless to pale yellow, fuming liquid with a sharp, pungent odor. It reacts vigorously with water, undergoing rapid hydrolysis to release hydrochloric acid and phosphorous acid, and must be handled under strictly anhydrous, well-ventilated conditions. Procorbay International supplies industrial-grade Phosphorus Trichloride serving as a fundamental chemical intermediate across pesticide, flame retardant, pharmaceutical, and specialty chemical manufacturing, valued for its exceptional reactivity as a phosphorylating and chlorinating agent.
• Phosphorus Trichloride is manufactured through the direct reaction of elemental phosphorus with chlorine gas under controlled conditions, followed by distillation to achieve the required industrial purity. Procorbay sources Phosphorus Trichloride from established inorganic chemical manufacturers with consistent quality control over purity and moisture-exclusion packaging integrity, given the compound's extreme sensitivity to atmospheric moisture.
• Industrially, Phosphorus Trichloride serves as one of the most important phosphorus-based chemical intermediates, functioning as the starting material for a vast range of organophosphorus compounds, including numerous agrochemical active ingredients (organophosphate pesticides and herbicides), flame retardant additives used in plastics and textiles, and pharmaceutical intermediates leveraging its reactive phosphorus-chlorine bonds for phosphorylation reactions. It also serves as a raw material in the production of phosphorous acid and various phosphonate esters used across water treatment, oilfield chemical, and specialty polymer applications.
• Given its foundational role across agrochemical, flame retardant, and pharmaceutical intermediate synthesis, Procorbay maintains reliable Phosphorus Trichloride supply with strict attention to moisture-protected packaging and handling protocols throughout the supply chain.
