| Use | Overview Aaromatic azo (AAzo) compounds are key raw materials and are widely used in the synthesis of organic dyes and food additives. Industrial production of AAzo's diazonium salt and diazonium salt coupling electron-rich aromatic compounds requires stoichiometric nitrite to form diazonium salts, resulting in a large amount of inorganic matter. Therefore, it is sustainable and highly selective in the process of AAzo formation with industrial applicability. Efforts have been made to use the catalytic oxidation of azobenzene-4-benzoic acid as an intermediate in pharmaceutical synthesis. If azobenzene-4-benzoic acid is inhaled, please move the patient to fresh air; if the skin is in contact, remove the contaminated clothes, rinse the skin thoroughly with soapy water and clear water, and see a doctor if you feel uncomfortable; if you are in contact with clear eyes, you should separate the eyelids, rinse with flowing water or normal saline, and see a doctor immediately; if you eat, rinse your mouth immediately, prohibit vomiting, and see a doctor immediately. |
