Used as a chiral building block in pharmaceutical synthesis, particularly in the development of biologically active compounds where stereochemistry plays a critical role. Its strained cyclobutane ring and functional groups enable unique reactivity, making it valuable for constructing complex molecular architectures. The hydroxyl and methanesulfonyl moieties allow for further derivatization, such as nucleophilic substitution or cross-coupling reactions. It is especially useful in medicinal chemistry for optimizing potency and selectivity in drug candidates targeting CNS disorders and inflammatory diseases.
