Used as a building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and peptidomimetics. Its strained cyclobutane ring enhances binding selectivity in drug design. Commonly employed in medicinal chemistry for creating enzyme inhibitors and receptor ligands. Also utilized in the preparation of specialty chemicals and chiral intermediates for asymmetric synthesis. Stable as the hydrochloride salt, making it suitable for storage and handling in industrial and laboratory settings.
