Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Shows utility in creating structurally complex molecules for drug discovery due to its rigid, polycyclic framework and functional handles for further modification. Often employed in studies targeting neurological disorders where pyridine-based scaffolds are relevant. Its ester and hydrochloride groups enhance solubility and reactivity, making it suitable for coupling reactions and salt formation in medicinal chemistry workflows.
