Used as a fluorinated surfactant or surface modifier in coatings and specialty materials due to its highly fluorinated carbon chain, providing strong water and oil repellency. The iodine end group allows for further chemical modification, making it useful in the synthesis of fluorochemical intermediates for electronics, medical devices, and water-repellent treatments on textiles or optical surfaces. Its low surface energy contributes to improved performance in lubricants and anti-fouling coatings. Also employed in research for creating self-assembled monolayers on surfaces where controlled wetting behavior is required.
