Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and specialty amines. Its cyclic structure with an amine functionality enables selective modifications for drug design, especially in creating conformationally constrained analogs. It is also employed in research settings for the preparation of ligands in catalysis and in the study of ring strain effects on amine reactivity. The hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous or polar reaction media.
