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 complex organic molecules due to the reactivity of the aldehyde group and the presence of the pyridinyl ring, which enhances binding affinity in biological systems. Commonly employed in cross-coupling reactions and condensation processes to form Schiff bases, which are valuable in medicinal chemistry and materials science. Also utilized in the fabrication of ligands for metal-catalyzed reactions, improving catalytic efficiency and selectivity.
