  • Applications

    1,3-Dioxolane, 2-(1-phenylethyl)- (CAS 4362-22-5) is used as an acetal-protecting group for carbonyls in organic synthesis, enabling protection of carbonyl functionality in multi-step sequences. In the chemical industry, it is commonly employed as an intermediate for the synthesis of complex compounds and pharmaceuticals. It may also function as a specialty solvent or reaction medium in industrial manufacturing, including coatings and plastics processing. Owing to the phenylethyl moiety, it can be considered an ingredient or intermediate for fragrance and personal care applications, with potential use as a fragrance note or fixative within regulatory formulation limits. Applications are subject to local regulations and formulation constraints.
