Used as a key intermediate in the synthesis of cephalosporin antibiotics, particularly in the production of third-generation cephalosporins like ceftazidime and ceftriaxone. Its structure enables beta-lactam ring integration, enhancing antibacterial activity against a broad spectrum of Gram-negative and some Gram-positive bacteria. Commonly employed in pharmaceutical research and development for creating semi-synthetic antibiotics with improved stability and resistance to beta-lactamases. Also utilized in the preparation of derivatives for structure-activity relationship studies in antimicrobial drug design.
