  • Applications

    Isovaleraldehyde (CAS 590-86-3) is primarily used as a fragrance ingredient in perfumery and cosmetics, providing fruity to malty notes; it is also used as a flavor ingredient to contribute notes in foods and beverages. It serves as a chemical intermediate for the synthesis of aroma esters and other fragrance compounds used in the flavor and fragrance industries. It is employed in household products and cleaners as an odorant to impart a pleasant scent. In industrial manufacturing, it may function as a reactive aldehyde building block for organic synthesis, enabling the production of aroma compounds and other specialty additives.
