Ethyl trans-2-octenoate is widely used in the flavor and fragrance industry due to its fruity and slightly green aroma. It is commonly incorporated into food products to enhance or mimic natural fruit flavors, particularly in items like candies, beverages, and baked goods. Additionally, it serves as a key ingredient in perfumes and cosmetic formulations, where it contributes to fresh and pleasant scent profiles. Its stability and compatibility with other ingredients make it a versatile choice for creating complex aromatic blends.
