  • Applications

    2-Ethyl-3,4-dihydroxyfuran (CAS 27402-93-3) is primarily used as an organic synthesis intermediate, serving as a building block for heterocyclic compounds and for pharmaceutical and agrochemical research. It may function as a diol precursor in polymer and coating formulations (polyesters, polyurethanes), enabling crosslinking and functionalization of materials. In fragrance and flavor chemistry, furanoid diol derivatives can be explored as aroma precursors or scent components. The compound is also evaluated for specialty chemical applications in materials and coatings, where the diol functionality supports tailoring of physical properties. Usage is typically governed by formulation requirements and regulatory constraints.
