Product Name	Triphosgene (Solid Phosgene Substitute) (Bis(trichloromethyl) Carbonate / BTC)
CAS NO.	32315-10-9
Formula & Weight	C₃Cl₆O₃ (MW: 296.75)
Chemical Structure
Technical Specifications	Appearance: White crystalline solid Assay (GC): ≥ 99.5% Melting Point: 79°C - 81°C Residue on Ignition: ≤ 0.1% Loss on Drying: ≤ 0.5% Solubility: Soluble in Ether, THF, Benzene, Hexane.
Key Applications	A versatile "One-Pot" carbonylating agent replacing toxic Phosgene gas: Pharmaceutical Synthesis: Reagent for synthesizing Chloroformates, Acid Chlorides, and Isocyanates. Used in the production of antibiotics (e.g., Mezlocillin, Azlocillin) and antiviral drugs. Agrochemicals: Essential for synthesizing carbamate pesticides and herbicides where precise stoichiometry is required. Polymer Chemistry: Used in the synthesis of Polycarbonates and polypeptide biodegradable polymers via ring-opening polymerization. Operational Safety: Offers exact dosing capability (solid form) and significantly reduced vapor hazard compared to liquid/gaseous Phosgene.
Packaging & Logistics	Packaging: 25kg Fiber Drum with double PE liners. Storage: Moisture Sensitive. Store in a cool, dry, well-ventilated area. Keep away from heat sources.
