Application:
2-Bromo-4'-Nitroacetophenone (CAS: 99-81-0) is used as raw materials for organic synthesis and pharmaceutical intermediates, etc. A pharmaceutical intermediate for the synthesis of chloramphenicol and the like. Preparation Method It is prepared by bromination of p-nitroacetophenone. The solvent chlorobenzene and p-nitroacetophenone are added into the reaction vessel, and a small amount of bromine is added dropwise at 18℃, the temperature is controlled at 26~28℃, and bromine is added dropwise. After dropping, the reaction is carried out for 1 hour, and the temperature is raised to drive out HBr, and the post-treatment is obtained. 99-81-0 - Risk and Safety Hazard Symbols: C - Corrosive Risk Codes: R34 - Causes burns Safety Description: S26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
