Phosphorus Trichloride in Bulk

Phosphorus trichloride is the gateway to almost all organophosphorus chemistry. It is the starting point for glyphosate, for phosphite antioxidants, for flame retardants and for a long list of pharmaceutical intermediates. It is also acutely hazardous and reacts violently with water, so supply is restricted to buyers with the necessary licences and engineered handling systems.

Applications

Declare your intended use when enquiring, as this is a scheduled chemical under international convention.

• Glyphosate and organophosphate agrochemical manufacture
• Phosphite antioxidants for polymers
• Flame retardant intermediates
• Chlorinating agent in pharmaceutical synthesis
• Plasticiser and lubricant additive manufacture

Safety, Handling and Compliance

PCl3 is a scheduled chemical under the Chemical Weapons Convention and reacts violently with water to release hydrogen chloride and phosphorous acid.

FAQs

Questions buyers commonly ask about phosphorus trichloride.

• Do I need a licence? Yes, and the consignment is declarable under CWC rules.
• Why does POCl3 content matter? It indicates oxidation during storage and affects reaction yield.
• How should it be stored? Dry, sealed and nitrogen blanketed, away from any moisture source.
• Can I get a sample? Only under the same licensing requirements.
• What documents are provided? GST invoice, batch CoA, SDS, TREM card and statutory declarations.
