    Butanoic acid, 2-hexenyl ester, (Z)- (CAS 56922-77-1) is an unsaturated ester primarily used as a fragrance ingredient. In perfumery it provides odorant notes with a green/fruit-like character and can act as a mild fixative in fragrance blends. Real-world applications include: fragrance and cosmetics/personal care formulations; household products such as air fresheners and detergents to impart scent; the aroma/fragrance sector as a fragrance precursor; coatings and inks that incorporate fragrance additives; and cleaning products where scent enhancement is desired.
