Used primarily as a fluorinated building block in the synthesis of specialty polymers and surfactants, this compound imparts exceptional water and oil repellency to materials. Its long perfluorinated chain enhances thermal and chemical stability, making it valuable in coatings for textiles, electronics, and aerospace components where durability and resistance to harsh environments are critical. It is also employed in the preparation of fluoroelastomers and lubricants designed for extreme conditions. Due to its hydrophobic and oleophobic properties, it finds use in formulations for stain-resistant finishes and anti-fouling surfaces.
