Used as an intermediate in the synthesis of pharmaceuticals and biologically active compounds. It participates in the preparation of heterocyclic molecules, particularly in the formation of quinazolines and other nitrogen-containing rings that show antimicrobial, anti-inflammatory, or anticancer activity. Its aldehyde and amide functional groups allow for diverse chemical modifications, making it valuable in medicinal chemistry research and development of new drug candidates. Also employed in the production of dyes and fluorescent probes due to its reactivity and structural properties.
