Used as a chiral intermediate, specifically the (S)-isomer, in the synthesis of antibacterial agents, particularly in the production of oxazolidinone-class antibiotics like linezolid and tedizolid. These antibiotics target gram-positive resistant bacteria, such as MRSA and VRE. Its stereochemistry enables selective reactions in asymmetric synthesis, making it valuable in pharmaceutical development. It plays a crucial role in carbon-carbon bond formation or functional group addition at specific molecular positions, ideal for laboratory drug development requiring high (S)-isomer purity. Commonly employed to introduce activated chiral building blocks in complex molecule assembly.
