Used as a key intermediate in organic synthesis, particularly in the preparation of pyridine-containing compounds with pharmaceutical relevance. It participates in cycloaddition and coupling reactions to build complex heterocyclic frameworks found in bioactive molecules. Commonly employed in the development of kinase inhibitors and other medicinal agents targeting cancer and inflammatory diseases. Its conjugated system makes it valuable in materials science for designing fluorescent probes and optoelectronic materials. Also utilized in catalysis research due to its ability to coordinate with metal centers in transition metal complexes.
