  • Applications

    1,3-Dioxolane-4-methanol, 2-phenyl- is typically used as a synthetic intermediate in organic chemistry, serving as a building block for downstream derivatives in fragrance materials, cosmetics, and pharmaceutical manufacturing. It may be evaluated as a precursor for aromatic fragrance compounds and for specialty polymers or resins by functionalizing the hydroxymethyl group or the dioxolane ring. In fragrance and cosmetics, it can act as a feedstock or anchoring intermediate for aroma materials; in polymers, coatings/inks, and adhesives, it can serve as a reactive intermediate for monomer synthesis or crosslinking functionality. Its hydroxymethyl group also allows consideration as a solvent or processing aid in formulation development at small scale, subject to local regulations and formulation limits.
