Used in the synthesis of fluorescent dyes and optoelectronic materials due to its conjugated aromatic structure and ability to form stable imidazole derivatives. It serves as a key intermediate in preparing ligands for metal-organic frameworks (MOFs) and coordination compounds with potential use in sensors and catalysis. Its aldehyde group allows for easy functionalization, making it valuable in pharmaceutical research for building bioactive molecules, particularly in developing antimicrobial and anticancer agents. Also employed in the preparation of Schiff bases, which exhibit enhanced photophysical properties for use in imaging and detection technologies.
