  • Applications

    For 5-(2,6-Dimethylheptyl)-3-ethyldihydro-2(3H)-furanone (CAS 160775-28-0), this long-chain gamma-lactone is employed primarily as a fragrance ingredient and odorant in perfumery, where it contributes woody/musky notes and can function as a fixative to extend scent persistence. It is commonly evaluated for cosmetics and personal care formulations as a fragrance component or scent modifier, and may also be used in household products such as air fresheners to impart lasting aroma. In addition, the compound serves as an intermediate in fragrance synthesis and may be explored as a flavor/aroma additive in restricted food applications, subject to regulatory approvals; it can also find use as a specialty building block in industrial manufacturing of aroma-related formulations.
