Used in research to study the mechanisms of neurodegenerative diseases, particularly Parkinson's. It serves as a labeled compound in pharmacokinetic and metabolic studies, helping to trace and understand the pathways and effects of deprenyl derivatives. It is also employed in the development of therapeutic agents targeting monoamine oxidase inhibition, which is crucial for managing neurological conditions. Additionally, it aids in the investigation of dopamine regulation and its role in brain function.
