Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals. Its structure contains both a protected amine (Boc group) and a hydroxyl-functionalized cyclobutane ring, making it valuable for constructing complex molecules. The hydroxyl group allows for further functionalization, such as esterification or ether formation, while the Boc-protected amine can be deprotected to release a free amine for amide bond formation or other coupling reactions. Commonly employed in medicinal chemistry for building constrained ring systems that influence potency, selectivity, and metabolic stability in drug candidates.
