Ethyl 2-methylpent-2-enoate is used as a flavor and fragrance ingredient due to its fruity, green, and apple-like notes. It is commonly found in artificial flavorings for food products and in perfumery to add fresh, fruity nuances. Additionally, it serves as an intermediate in organic synthesis for pharmaceuticals and fine chemicals. Featuring an α,β-unsaturated ester structure, its reactivity makes it suitable for reactions such as Michael additions, nucleophilic additions, and esterifications in lab-scale chemical development.
