Used primarily in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds. It serves as a building block for developing agents targeting central nervous system disorders due to its structural similarity to neurotransmitter modulators. Commonly employed in the creation of serotonin and dopamine receptor ligands, aiding in the study of depression, anxiety, and schizophrenia. Also utilized in the development of kinase inhibitors for cancer research. Its versatility in forming salt forms enhances solubility and bioavailability in drug formulation studies.
