Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting neurological and inflammatory conditions. Its aldehyde functional group allows for further chemical modifications, such as condensation reactions, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its rigid scaffold and ease of derivatization. Also utilized in the preparation of receptor ligands and enzyme inhibitors where the dihydroquinoline core enhances binding affinity and selectivity.
