Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of vitamin B6 (pyridoxine) and related compounds. It plays a key role in forming the pyridine ring structure found in various bioactive molecules. Also employed in the development of agrochemicals and functional materials due to its reactive aldehyde and hydroxyl groups, which allow for further chemical modifications. Its derivatives are explored in medicinal chemistry for potential antimicrobial and antitumor activities.
