Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where stereochemistry is critical. Its enantiomeric purity makes it valuable in asymmetric synthesis, especially in the development of agrochemicals and fine chemicals. Commonly employed in the preparation of beta-substituted carboxylic acid derivatives, it serves as an intermediate in the manufacture of certain anti-inflammatory agents and neuroactive compounds. Its reactivity allows for easy transformation into esters, amides, and other functional groups, facilitating its integration into complex molecular architectures.
