Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of antidepressant and anticonvulsant drugs. Its stereochemistry plays a critical role in enhancing the selectivity and efficacy of active pharmaceutical ingredients. Commonly employed in the development of serotonin reuptake inhibitors due to its ability to influence neurotransmitter activity. Also utilized in research settings for asymmetric synthesis and the preparation of structurally complex bioactive molecules.
