Description

2,2,3,3,3-Pentafluoropropyl acrylate (CAS No. 356-86-5) is a high-purity fluorinated acrylate ester with the molecular formula C₆H₅F₅O₂. This specialty chemical is widely used in advanced polymer synthesis and surface modification due to its unique fluorinated side chain, which imparts exceptional hydrophobicity, chemical resistance, and low surface energy properties. The compound is supplied as a clear, colorless liquid with a characteristic mild odor, and it is highly reactive in radical polymerization reactions. It is particularly valued in the development of fluoropolymers, coatings, and adhesives where enhanced performance under extreme conditions is required. Proper storage under inert atmosphere and refrigeration is recommended to maintain stability and prevent premature polymerization.
