  • Applications

    Hex-3-en-1-yl butanoate (CAS 2142-93-0) is an unsaturated aliphatic ester derived from butanoic acid and hex-3-en-1-ol, used primarily as a fragrance ingredient. In perfumery, it functions as a middle- or top-note component with green, fresh character and may contribute to the odor profile of blends. It is also evaluated as a flavor/aroma compound for applications aiming to convey green, citrusy-fruity notes in food and beverage formulations within regulatory limits. In cosmetics and personal care, it serves as a fragrance ingredient in products such as moisturizers, shampoos, and cleansers. In household products and cleaning agents, it appears as a fragrance additive to impart characteristic scents in cleaners, detergents, and air fresheners. In industrial manufacturing, coatings, and inks contexts, it can be used as a fragrance additive or an intermediate in fragrance synthesis, subject to local regulations and formulation limits.
