Used as a key intermediate in the synthesis of fluorinated surfactants and specialty polymers, this compound imparts exceptional water and oil repellency to coatings, textiles, and electronic materials. Its dual hydroxyl groups allow for easy incorporation into polyurethane and epoxy systems, enhancing chemical resistance and surface durability. Due to the perfluorinated chain, it contributes to low surface energy, making it valuable in non-stick and anti-fouling applications. It is also employed in the formulation of fire-fighting foams and in the development of high-performance lubricants and release agents.
