Used as a key intermediate in the synthesis of linezolid, a synthetic antibiotic effective against Gram-positive bacteria, including drug-resistant strains such as MRSA (methicillin-resistant Staphylococcus aureus) and VRE (vancomycin-resistant enterococci). Its structure enables the formation of the core oxazolidinone ring system critical for antibacterial activity. It plays a vital role in pharmaceutical development for treating severe bacterial infections, especially in hospital settings where resistance to conventional antibiotics is a concern.
