  • Applications

    Benzyl 2-methylbutyrate (CAS 56423-40-6) is used in perfumery as an odorant with potential as a light fixative in fragrance formulations. In cosmetics and personal care, it serves as a fragrance ingredient in perfumes, lotions, and cleansers. In household products, it provides a fruity aroma in air fresheners, detergents, and cleaning products. It may be used as a flavor/aroma ingredient in permitted food formulations, subject to local regulatory limits. In industrial manufacturing, it can function as an intermediate for the synthesis of additional fragrance compounds or be added to plastics and coatings as an odorant to tune scent.
