Used in the synthesis of linezolid, a potent antibiotic belonging to the oxazolidinone class. It plays a key role as an intermediate in creating the core structure of linezolid, which is effective against Gram-positive bacterial infections, including drug-resistant strains like MRSA and vancomycin-resistant enterococci (VRE). Due to its stereochemistry, the (S)-configured intermediate ensures the correct spatial orientation required for biological activity in the final drug product. This compound is therefore critical in pharmaceutical manufacturing for producing antimicrobial agents used in severe hospital-acquired infections.
