Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and anti-inflammatory agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions to introduce pyrazole moieties into target molecules, enhancing biological activity and binding specificity. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies during drug discovery.
