2,2,2-Trichloroethyl chloroformate (CAS 17341-93-4) is a reactive chloroformate derivative used primarily in organic synthesis for introducing trichloroethoxycarbonyl (Troc) protecting groups in peptide and drug manufacturing. In analytical laboratories, it also serves as a reagent for determining pethidine by gas chromatography. It appears as a colorless to pale yellow liquid with a pungent odor, requiring careful handling due to its high reactivity and toxicity. The molecular formula is ClCOOCH2CCl3, with a molecular weight of 211.86 g/mol. Store at 2 to 8°C in a cool, well-ventilated area, away from incompatible substances. The product carries a **Danger** signal word under GHS classification. Molekula supplies 2,2,2-Trichloroethyl chloroformate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
