Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system active compounds. Its stereochemistry enables high enantioselectivity in drug synthesis, improving efficacy and reducing side effects. Also employed in the development of agrochemicals where chirality influences biological activity. The carboxylic acid functionality allows for easy derivatization into amides, esters, or other functional groups for structure-activity relationship studies.
