2-Methyloctanoic acid is widely used in the flavor and fragrance industry due to its unique fatty and waxy odor profile. It serves as a key ingredient in creating synthetic flavors, particularly in mimicking cheese and dairy products, enhancing their savory and creamy characteristics. Additionally, it is utilized in perfumery to add depth and complexity to fragrance compositions, often contributing to woody or earthy notes. In organic synthesis, it acts as a building block for producing esters and other derivatives, which are further employed in various industrial applications. Its antimicrobial properties also make it a potential candidate for use in preservatives and disinfectants.
