Used in biochemical and pharmaceutical research as a building block for synthesizing peptide-like structures and neuroactive compounds. It serves as a precursor or intermediate in the development of drugs targeting neurological disorders due to its structural similarity to amino acids involved in neurotransmission. Also utilized in studies involving enzyme inhibition and receptor binding, particularly in relation to pyridine-containing bioactive molecules. Its hydrochloride salt form enhances solubility and stability in aqueous solutions, making it suitable for in vitro and in vivo experiments.
