Triphosgene, 98%

About Triphosgene, 98%

Triphosgene is a peptide synthesis reagent (Synthesis grade) carrying the CAS registry number 32315-10-9 with a typical assay of 98%. Its molecular formula is C3Cl6O3 and its molecular weight is 296.7 g/mol. Its systematic (IUPAC) name is bis(trichloromethyl) carbonate. Alternative names: Methanol, trichloro-, carbonate (2:1) and bis(trichloromethyl)carbonate.

It is supplied as white powder or crystals. Literature values give a melting point of 79-83 °C and a boiling point of 203-206 °C. Store sealed in a dry, well-ventilated location away from incompatible materials. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span peptide coupling, solid-phase peptide synthesis, bioconjugation and organic synthesis. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.

Available in 100 g, 500 g, 5 kg and 4 x 25 kg packs, Triphosgene is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
