HONB (N-hydroxy-5-norbornene-2,3-dicarboxylimide) is a specialized organic intermediate derived from maleic anhydride and cyclopentadiene via imidization. Its molecular formula is C10H9NO4. While often used as a protecting group or linker in synthesis, specific CAS registration data for this exact nomenclature requires verification against proprietary databases.
Store in a cool, dry place under inert atmosphere to prevent hydrolysis. Personnel must wear appropriate PPE including chemical-resistant gloves and eye protection due to potential irritant properties. Not intended for direct clinical use without further derivatization and regulatory approval.
