Uses   The perfluoroalkyl ethyl series is an important starting material for producing the corresponding alcohol, thiol, sulfonyl

chloride, and other fluorinated intermediates.  These intermediates can be further modified to produce various fluorinated

surfactants, fluorinated surface coatings, and other fluorinated fine chemicals.  They have excellent and unique properties

including low surface tension, high heat stability, high chemical resistance, as well as water & oil repellency.
