Used in research for its potential neuroprotective properties, particularly in studies related to Parkinson’s disease. It serves as a metabolic precursor or intermediate in the synthesis of certain alkaloids and bioactive compounds. Investigated for its antioxidant effects in neuronal cells, helping to mitigate oxidative stress. Also utilized as a reference standard in analytical methods for detecting tetrahydroisoquinoline derivatives in biological samples. Its derivatives are explored for pharmacological activity in central nervous system disorders.
