Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active molecules. Its aldehyde and ether functional groups allow for versatile chemical modifications, making it valuable in constructing complex organic frameworks. Commonly employed in cross-coupling reactions, condensations, and reductive amination processes to build nitrogen-containing heterocycles. Also utilized in medicinal chemistry for the preparation of pyridine-based drug candidates targeting cancer, inflammation, and central nervous system disorders.
