Used in the synthesis of β-lactam antibiotics, particularly as a key intermediate in the production of cephalosporins. It contributes to the core structure of these antibiotics, enhancing their stability and antimicrobial activity. Also employed in the development of new pharmaceuticals due to its ability to participate in ring-forming reactions and its bioisosteric properties. Additionally, it finds use in medicinal chemistry for designing compounds with anti-inflammatory, antiviral, and anticancer activities.
