Widely used as a key intermediate in the production of semi-synthetic penicillins. It serves as the core structure for modifying side chains to develop antibiotics with improved stability, broader spectrum, or resistance to beta-lactamases. Commonly employed in the synthesis of ampicillin, amoxicillin, and other beta-lactam antibiotics. Its amino group allows for chemical acylation, enabling the creation of various derivatives tailored for specific bacterial infections. Plays a critical role in pharmaceutical manufacturing due to its versatility in antibiotic development.
