Used in the synthesis of pharmaceutical intermediates, particularly in the development of antihypertensive and cardiovascular drugs. Acts as a chiral building block in organic synthesis, enabling the construction of complex molecules with high stereoselectivity. Also employed in the preparation of bioactive compounds and enzyme inhibitors due to its structural similarity to endogenous dicarboxylic acids. Its aromatic and carboxylic functional groups allow for diverse chemical modifications, making it valuable in medicinal chemistry research and drug discovery.
