Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and kinase inhibitors. Its bromophenyl and hydroxyl-functionalized oxetane structure provides a rigid scaffold that enhances metabolic stability and binding affinity in drug molecules. Commonly employed in cross-coupling reactions due to the bromine handle, enabling the construction of complex organic frameworks for medicinal chemistry research. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies.
