It is commonly incorporated into food products to enhance or replicate natural flavors, particularly in items such as dairy products, beverages, and processed foods. Additionally, it is a key component in perfumes and cosmetics, where it adds a fresh, natural scent. Its ability to blend well with other aroma compounds makes it a versatile ingredient in creating complex and appealing fragrances.
