Isobutyric acid is widely used in the food and beverage industry as a flavoring agent due to its strong, pungent odor and sour taste. It is often incorporated into dairy products, baked goods, and confectionery to enhance flavor profiles. In the fragrance industry, it serves as a key ingredient in the synthesis of esters, which are used in perfumes and scented products. Additionally, isobutyric acid is utilized in the production of pharmaceuticals, where it acts as an intermediate in the synthesis of various drugs and active compounds. Its applications also extend to the manufacturing of plastics, resins, and coatings, where it functions as a precursor or additive to improve material properties. In agriculture, it is employed as a component in animal feed to promote growth and improve digestion.
