(S)-(-)-2-Methylbutyric acid is widely used in the flavor and fragrance industry due to its distinct fruity and cheesy aroma. It is a key ingredient in the production of artificial flavors, particularly for cheese, butter, and other dairy products, enhancing their savory and tangy profiles. Additionally, it serves as a building block in the synthesis of esters, which are commonly employed in perfumes and food flavorings. In the pharmaceutical sector, it is utilized as an intermediate in the production of certain active pharmaceutical ingredients. Its chiral nature also makes it valuable in asymmetric synthesis for creating specific enantiomers of complex molecules.
