Ethyl 5-methylhex-5-enoate is primarily used in the fragrance and flavor industry due to its pleasant fruity and green aroma. It is often incorporated into perfumes, colognes, and scented products to add a fresh, natural note. In flavor formulations, it enhances the taste of fruit-based products such as beverages, candies, and desserts, providing a sweet and slightly tangy profile. Additionally, it serves as an intermediate in organic synthesis, particularly in the production of more complex chemical compounds used in various industrial applications. Its versatility and appealing sensory characteristics make it a valuable ingredient in both consumer and industrial contexts.
