Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and antiviral agents. It serves as a building block in medicinal chemistry due to its ability to form stable heterocyclic structures that interact with biological targets. Commonly employed in research settings for designing drugs that target thrombin and other serine proteases involved in blood coagulation and inflammatory pathways. Also utilized in the preparation of pyrazole-based compounds with potential anticancer and antimicrobial activity. Its reactivity and structural features make it valuable in generating compound libraries for high-throughput screening in drug discovery.
