Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It participates in cyclization reactions to form pyridine, pyrimidine, and quinoline derivatives, which are common scaffolds in pharmaceuticals. Its structure allows for functionalization in antitumor, antimicrobial, and anti-inflammatory agent development. Commonly employed in Knoevenagel condensation reactions to build conjugated systems for dyes and optoelectronic materials. Also utilized in the synthesis of agrochemicals due to its reactivity with nucleophiles and electrophiles.
