  • Applications

    1-(Furan-2-yl)pent-1-en-3-one (CAS 770-48-9) is commonly used as a chemical intermediate in organic synthesis. In fragrance and cosmetics, it serves as a fragrance intermediate and building block for formulations with characteristic aroma; in coatings, inks, and polymer systems, it can function as a reactive enone monomer or crosslinking precursor for specialty formulations; in industrial manufacturing it is employed as a building block for multi-step syntheses; and it may be evaluated as a synthetic intermediate for pharmaceutical or agrochemical development, depending on target molecules and safety constraints. Subject to local regulations and formulation limits.
