Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly duloxetine, a selective serotonin and norepinephrine reuptake inhibitor (SNRI) used for treating depression and anxiety. It plays a key role in constructing the molecular framework of the drug by introducing specific functional groups in a controlled manner. The carbamate structure provides protection and stability during the synthesis process, enabling efficient production and quality control of the final product. Commonly employed in research settings for developing analogs with enhanced pharmacokinetic profiles.
