Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its rigid cyclobutane scaffold with defined stereochemistry makes it valuable for designing enzyme inhibitors and receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to influence potency, selectivity, and metabolic stability in drug candidates. Also utilized in the preparation of bioactive molecules targeting neurological disorders and inflammatory conditions.
