Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs such as cilnidipine, a calcium channel blocker. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems in medicinal chemistry. Also employed in the development of agrochemicals due to its ability to enhance bioactivity in certain plant growth regulators. Its carboxylic acid and hydroxyl groups provide sites for derivatization, enabling use in peptide coupling and prodrug design.
