Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to its ability to undergo condensation and coupling reactions. Commonly employed in the construction of Schiff bases and imines that exhibit antimicrobial or anti-inflammatory activity. Also utilized in the fabrication of sensors and functional materials owing to the presence of pyridine and aldehyde groups, which facilitate metal coordination and further chemical modifications.
