Used in pharmaceutical research and development, particularly in the study of neurodegenerative disorders such as Parkinson’s disease. It serves as a metabolic intermediate and precursor in the synthesis of dopamine, making it valuable in experimental models to support dopaminergic function. Commonly employed in laboratory settings to investigate neurotransmitter pathways and to develop novel drug delivery systems targeting the central nervous system. Also utilized in analytical chemistry as a reference standard for detecting catecholamine metabolites in biological samples.
