Description

2-(Trifluoromethyl)oxirane (CAS No. 359-41-1) is a highly versatile fluorinated epoxide with the molecular formula C₃H₃F₃O. This specialized chemical is widely utilized in organic synthesis, pharmaceutical intermediates, and advanced material science due to its reactive oxirane ring and trifluoromethyl group. Its unique structure enables selective functionalization, making it valuable for researchers developing fluorinated compounds with enhanced stability and reactivity. The compound is supplied as a high-purity liquid (typically ≥98% by GC) and should be stored under inert conditions to prevent polymerization. Suitable for use in Grignard reactions, nucleophilic ring-opening, and as a building block for agrochemicals or bioactive molecules.
