Widely used in organic synthesis, particularly in the preparation of heterocyclic compounds. It serves as a key building block for pharmaceuticals, agrochemicals, and dyes. Its active methylene group and multiple functional groups (amino, cyano, ester) allow for versatile reactivity, enabling cyclization reactions to form pyrimidines, pyridines, and other nitrogen-containing rings. Commonly employed in the synthesis of calcium channel blockers, antiviral agents, and kinase inhibitors. Also utilized in the production of fine chemicals and intermediates where complex molecular architectures are required. Its ease of transformation makes it valuable in both academic research and industrial drug development.
