Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of anticonvulsant drugs. It serves as a key intermediate in the preparation of beta-hydroxy-gamma-aminobutyric acid derivatives, which modulate neurotransmitter activity in the central nervous system. Its stereochemistry makes it valuable for developing enantiomerically pure active pharmaceutical ingredients. Also employed in the research and development of enzyme inhibitors and neuroactive compounds.
