  • Applications

    Propanoic acid, 2-methyl-, 3-methylpentyl ester (CAS 84254-84-2) is used as a fragrance ingredient and odorant in perfumery and cosmetics, contributing fruity or green notes in formulations. It also serves as a solvent and processing aid in fragrance, flavor, and personal care products, and as an intermediate for fragrance and flavor synthesis in industrial manufacturing. In household products, it may function as a fragrance solvent and odor carrier in cleaners and air fresheners. In coatings and inks, it can act as a solvent or fixative to influence evaporation and scent retention. In polymer formulations, it is sometimes used as a plasticizer or processing aid to modify flexibility and workability.
