Used as a key intermediate in the synthesis of β-lactam antibiotics, particularly in the production of cephalosporin class drugs. Its structure allows for effective coupling with other pharmacophores to enhance antimicrobial activity. Also employed in the development of novel heterocyclic compounds with potential biological activity, including anti-inflammatory and antiviral agents. Its phenolic and amino groups provide sites for chemical modification, making it valuable in medicinal chemistry research and drug design.
