Used as a key intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. Its structure supports the formation of heterocyclic systems found in certain anti-inflammatory and antimicrobial agents. Commonly employed in medicinal chemistry for constructing fused ring systems like benzodiazepines and other nitrogen-sulfur containing scaffolds. Also utilized in the preparation of kinase inhibitors and central nervous system active agents due to its ability to interact with enzyme active sites and receptors. Its ester and amino functional groups allow for further derivatization, making it valuable in combinatorial chemistry and drug discovery research.
