Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive nitrile and heterocyclic structure. Its electron-deficient ring makes it suitable for cycloaddition reactions, particularly in constructing complex nitrogen-containing compounds. Commonly employed in the development of fungicides and herbicides. Also applied in materials science for the preparation of specialty polymers and fluorescent dyes. Its versatility in click chemistry and ability to undergo nucleophilic substitution support its use in drug discovery and combinatorial chemistry platforms.
