  • Applications

    Hexafluoroisopropanol (CAS 920-66-1) is a highly polar, protic, non-nucleophilic solvent used as a specialty medium in organic synthesis and materials processing. In practice it is commonly used as a solvent for challenging substrates and for peptide and other biopolymer chemistry, where its strong hydrogen-bonding ability helps solubilize and stabilize reactive intermediates. It serves as a processing solvent for fluorinated polymers and high-Tg materials, enabling dissolution, film formation, and coating formulation. It is also used as an analytical and NMR solvent for difficult-to-dissolve solutes, and as a component in coatings and photoresist formulations in the electronics industry to improve wetting and film properties. As with all fluorinated solvents, its use is subject to local regulations and formulation limits.
