Used primarily in medical research, particularly in studies related to neurological disorders. It serves as a reference compound in the development of treatments for conditions like Huntington's disease and other movement disorders. Its role is crucial in understanding the mechanisms of vesicular monoamine transporters, which are involved in the regulation of neurotransmitters. This compound aids in the exploration of potential therapeutic agents by providing insights into the modulation of neurotransmitter release and uptake. Additionally, it is utilized in pharmacological assays to evaluate the efficacy and selectivity of new drugs targeting the central nervous system.
