Used as a flavoring agent in the food industry due to its fruity odor, methyl 2-pentenoate contributes to the formulation of artificial flavors, particularly for apple, pineapple, and other tropical fruit profiles. It is also employed in fragrance compositions for cosmetics and soaps, adding fresh, green, and fruity notes. In chemical synthesis, it serves as an intermediate in the production of pharmaceuticals and agrochemicals, benefiting from its reactive double bond and ester functionality.
