Used in the synthesis of active pharmaceutical ingredients, particularly in the development of central nervous system agents. It serves as a key chiral intermediate in the production of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant drugs. Its structural features allow for high receptor selectivity, improving drug efficacy and reducing side effects. Commonly employed in research and industrial settings for building complex drug molecules due to its functional handle and stereochemical purity.
