Used primarily as an intermediate in the synthesis of fluorosurfactants and surface treatment agents. Its fluorinated chain provides strong hydrophobic and oleophobic properties, making it valuable in coatings for textiles, paper, and leather to impart water and stain resistance. Also employed in fire-fighting foams due to its ability to reduce surface tension and stabilize foam. Additionally, it finds use in electroplating and semiconductor manufacturing for improving wetting and leveling properties in chemical formulations.
