Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules targeting neurological and inflammatory disorders. Its aldehyde functionality allows for easy derivatization, enabling the formation of imines, hydrazones, or other carbon-carbon bonds critical in drug design. Commonly employed in medicinal chemistry for scaffold modification to enhance potency, selectivity, and metabolic stability of lead compounds. Also utilized in the preparation of heterocyclic systems found in central nervous system agents and antiviral drugs.
