4-Ethylphenyl acetate is primarily used in the fragrance and flavor industry due to its pleasant, fruity, and floral aroma. It is commonly incorporated into perfumes, colognes, and cosmetic products to add a sweet, slightly balsamic scent. In food flavoring, it is utilized to enhance the taste of various products, particularly those requiring a fruity or floral note. Additionally, it serves as an intermediate in the synthesis of other aromatic compounds, contributing to the development of more complex fragrances and flavors. Its stability and compatibility with other ingredients make it a versatile choice in both personal care and food applications.
