  • Applications

    alpha-Methylcinnamic alcohol is primarily used as a building block in the synthesis of fragrance and flavor compounds. It can be converted into esters and other aroma chemicals for use in perfumery and cosmetics. It may be evaluated as a fragrance ingredient or odorant in consumer products and serves as a precursor for aroma compounds in food-related applications. It also finds use in coatings/inks and in household cleaning products as a fragrance additive. Its use is subject to local regulations and formulation limits.
