Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its brominated aromatic structure and functionalized cyclobutane ring make it valuable for constructing complex molecules through cross-coupling reactions or nucleophilic substitutions. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting neurological disorders. The ester and hydroxyl groups allow further derivatization, enabling the preparation of amides, acids, or ethers for enhanced bioavailability or receptor binding.
