Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of pyrazoles and triazoles, which are important scaffolds in pharmaceuticals and agrochemicals. It serves as a building block in click chemistry reactions, especially in the formation of nitrogen-containing rings via cycloadditions. Commonly employed in medicinal chemistry for the development of bioactive molecules, including kinase inhibitors and antimicrobial agents. Also utilized in polymer science to introduce functional groups that enhance cross-linking or material stability.
