2-Pentadecanone is primarily used in the flavor and fragrance industry due to its waxy, musky odor. 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 production of synthetic flavors to mimic natural aromas in food products. In industrial applications, it acts as an intermediate in the synthesis of other chemicals, particularly in the development of surfactants and lubricants. Its unique properties also make it useful in research as a reference compound in analytical studies.
