Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of nitrogen-containing heterocyclic compounds. Commonly employed in the development of fluorescent dyes and optoelectronic materials due to its conjugated structure. Also utilized in research for synthesizing potential bioactive molecules, including antimicrobial and anticancer agents. Its aldehyde group allows for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
