It serves as a key ingredient in the formulation of perfumes, cosmetics, and personal care products, where it adds a subtle, long-lasting scent. Additionally, it is employed in the food industry to enhance the flavor profile of various products, particularly in creating fruity or creamy notes. Its stability and compatibility with other compounds make it a versatile choice for blending in both aromatic and edible applications.
