  • Applications

    2-Furanacetaldehyde (CAS 15022-16-9) is primarily used as an organic synthesis intermediate across several applications: in fragrance and flavor chemistry as a building block for furan-containing aroma compounds and derivatives; in polymers and specialty plastics as a precursor for furan-based monomers, resins, and coatings; in cosmetics and personal care as a fragrance precursor or intermediate in scent formulations; in pharmaceutical and agrochemical research as a synthetic building block for heterocyclic and other specialty intermediates; and in laboratory-scale synthesis where it can be converted to derivatives such as 2-furylmethanol for further transformations.
