2-Nonyl acetate is widely used in the fragrance and flavor industry due to its pleasant, fruity, and slightly floral aroma. It is commonly incorporated into perfumes, colognes, and personal care products to add a fresh, green note. In flavor formulations, it is used to impart a fruity character to food and beverage products, particularly in citrus and tropical fruit flavors. Additionally, it serves as a solvent or intermediate in the synthesis of other chemical compounds. Its versatility and appealing scent make it a valuable ingredient in both cosmetic and food applications.
