  • Applications

    3-(Prop-2-en-1-yl)oxolan-2-one (CAS 10491-63-1) is an allyl-substituted gamma-butyrolactone primarily used as an organic synthesis intermediate and as a reactive monomer in polymer chemistry. It can undergo ring-opening polymerization to yield polyesters bearing pendant allyl groups, enabling post-polymerization crosslinking in coatings, inks, and adhesive formulations. The allyl functionality also supports UV- or radical-curing resin systems, expanding its use in industrial coatings and laminates. It may serve as a precursor in the synthesis of fragrance compounds, contributing to perfumery notes, and as a versatile building block for pharmaceutical intermediates. Its use is subject to local regulations and formulation limits.
