  • Applications

    4-Methyl-3-pentylfuran-2(5H)-one (CAS 142227-90-5) is primarily used as an odorant in fragrance applications, delivering fruity, tropical notes in perfumery formulations. It is often evaluated as a fragrance ingredient in cosmetics and personal care products, as well as in household cleaners and odor-emitting products to impart scent. In industrial manufacturing, it can serve as an intermediate or building block for other fragrance materials and specialty lactones. The compound may also be considered for incorporation in coatings or inks as a scent additive, and its use is typically subject to local regulations and formulation limits.
