Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds. It serves as a building block for drugs targeting central nervous system disorders due to its structural similarity to neurotransmitters. Its amine functionality and piperidine ring make it suitable for developing receptor ligands, particularly in the design of serotonin and dopamine modulators. Also employed in the development of novel analgesics and antidepressants. Its dihydrochloride form enhances solubility and stability, which is beneficial for formulation in early-stage drug development.
