Description

2,2,2-Trifluoroethanesulphonicacid CAS NO 1827-97-0 is a highly versatile and potent organic acid, valued for its exceptional acidity and stability as a trifluoromethanesulfonic acid (triflic acid) analog. Its unique combination of strong acidity and trifluoroethyl group makes it a powerful reagent and catalyst in demanding synthetic transformations. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce fluorine motifs or leverage superacidic conditions.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing the trifluoroethyl group to enhance metabolic stability and bioavailability.
• Catalyst & Reagent: Employed as a highly effective acid catalyst in organic synthesis, including esterifications, alkylations, and cyclization reactions where strong, non-nucleophilic acids are required.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the trifluoroethyl moiety can improve product efficacy and environmental profile.
• Polymer & Material Science: Serves as a monomer or modifying agent for creating specialty polymers with enhanced chemical resistance, thermal stability, or unique surface properties.
• Electrolyte Additive: Investigated for use in advanced battery systems, such as lithium-ion batteries, to improve electrolyte stability and performance at high voltages.
• Laboratory Research: A valuable reagent in academic and industrial R&D for developing new fluorination methodologies and studying superacid chemistry.
