Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of cardiovascular drugs and antihypertensive agents. It serves as a building block in medicinal chemistry due to its nitrogen-containing heterocyclic structure, which can enhance binding affinity to biological targets. Also employed in the preparation of agrochemicals and functionalized ligands for catalysis. Its hydroxyl group allows for easy derivatization, making it valuable in structure-activity relationship studies and library synthesis for drug discovery.
