Used primarily in pharmaceutical research as an intermediate in the synthesis of bioactive compounds. It serves as a building block for drugs targeting central nervous system disorders due to its structural similarity to neurotransmitter modulators. Commonly employed in the development of antipsychotics, antidepressants, and anxiolytic agents. Its functional groups allow for easy modification in medicinal chemistry, enabling the creation of novel derivatives with improved selectivity and potency. Also utilized in the preparation of receptor ligands, particularly for serotonin and dopamine receptors. Widely applied in structure-activity relationship (SAR) studies to optimize drug candidates.
