Used as a key intermediate in the synthesis of β-lactam antibiotics, particularly carbapenems and penems, which are broad-spectrum antibiotics effective against resistant bacterial strains. Its structure provides the core β-lactam ring essential for inhibiting bacterial cell wall synthesis. The benzoyloxy group at the 4-position enhances reactivity and selectivity during side chain modifications, enabling the development of more potent and stable antibiotic derivatives. Widely utilized in pharmaceutical research and industrial production of advanced antimicrobial agents.
