Used in biochemical research as a precursor or intermediate in the synthesis of amino acids and peptides. Serves as a reagent in studies involving amino group reactivity and enzyme substrates, particularly in neurochemistry due to structural similarity to excitatory neurotransmitters. Also applied in the development of pharmaceutical compounds where controlled release of amino functionalities is required. Its dihydrochloride form enhances solubility and stability in aqueous solutions, making it suitable for use in physiological assays and drug formulation studies.
