Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and analgesics. It serves as a building block for active pharmaceutical ingredients (APIs) due to the presence of both amine and amide functional groups, which allow for further chemical modifications. Commonly employed in the preparation of serotonin and norepinephrine reuptake inhibitors. Also utilized in research settings for the development of novel bioactive molecules and in medicinal chemistry for structure-activity relationship (SAR) studies.
