Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for branched-chain amino acid derivatives and plays a role in the synthesis of certain anti-inflammatory and antimicrobial agents. Its keto acid structure allows for facile transformation into amines, esters, and other functionalized compounds, making it valuable in medicinal chemistry research. Also employed in the development of biodegradable polymers and as a precursor in flavor and fragrance compounds due to its aliphatic chain and functional reactivity.
