  • Applications

    2-Propenylfuran (allylfuran, CAS 10599-55-0) is a versatile research building block that leverages the dual reactivity of the furan ring (electron-rich diene for Diels-Alder and electrophilic substitution) and the allyl side chain (amenable to epoxidation, hydroboration-oxidation, ozonolysis, selective Wacker/oxidations, and cross-metathesis), enabling its use as an intermediate to access substituted furans, dihydrofurans/benzofurans, and other heterocyclic scaffolds; in materials science it serves as a functional monomer/coupling unit—its allyl group allows free-radical and thiol-ene curing while the furan nucleus provides reversible Diels-Alder junctions with maleimides to build self-healing, reprocessable polymer networks, or to graft furan functionality onto silicones, polyurethanes, and surfaces via hydrosilylation/further modification; in medicinal and agrochemical discovery it is employed as a precursor/anchoring motif to diversify furan-containing libraries for SAR studies; and in food/analytical science it is used as a GC-MS reference/internal standard and as a model aroma component in thermal-processing studies to monitor formation pathways of furanic volatiles; these applications are typically limited to research use and do not imply approval for direct use in foods, drugs, or cosmetics.
