Acetoin(CAT: R059259), also known as 3-hydroxy-2-butanone, is a naturally occurring α-hydroxy ketone widely used in the food, fragrance, and pharmaceutical industries. It has a pleasant, buttery aroma and is commonly employed as a flavoring agent and fragrance component in dairy, baked goods, and cosmetic formulations. In biotechnology and microbiology, acetoin serves as a key metabolic intermediate and a diagnostic marker in the Voges–Proskauer test for bacterial fermentation. Additionally, it plays a role in the biosynthesis of biofuels and biodegradable plastics.
