Application
2-Methyl-4-pentenoic acid (CAS 1575-74-2) is an unsaturated branched-chain fatty acid with a powerful, sweet, fruity, and slightly sharp aroma reminiscent of pineapple, apple, and berry. It is naturally found in certain fruits and used as a flavoring agent (FEMA 3511) to impart juicy, tropical fruit notes to beverages, baked goods, candy, ice cream, and chewing gum. In the fragrance industry, it contributes a fresh, fruity, and slightly green nuance to perfumes, colognes, shampoos, and soaps, often enhancing top notes in floral and citrus accords. It also serves as a versatile intermediate in the synthesis of other aroma chemicals, pharmaceuticals, and agrochemicals, particularly for producing esters with enhanced fruity profiles. Its unique structure allows for selective transformations in organic synthesis. High-purity grade ensures consistent performance in sensitive flavor and fragrance applications.
