Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antidepressants. It serves as a building block in the preparation of selective serotonin reuptake inhibitors (SSRIs) and related compounds due to its structural compatibility with bioactive molecules. Also employed in the production of agrochemicals and fine chemicals where chlorinated aromatic amines are required. Its hydrochloride salt form enhances stability and solubility, facilitating handling and reaction efficiency in industrial processes.
