Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals. The structure features an azetidine ring substituted with a 2,2,2-trifluoroethyl group at position 1 and a hydroxyl group at position 3, supporting the development of enzyme inhibitors and receptor modulators. The trifluoroethyl moiety enhances lipophilicity, metabolic stability, and membrane permeability, while the hydroxyl and azetidine groups enable hydrogen bonding and structural rigidity, improving binding affinity in drug molecules. Commonly applied in medicinal chemistry for optimizing pharmacokinetic properties such as solubility and bioavailability. Widely used in the design of fluorinated drug candidates.
