Usage 1: It is mainly used for research on the effects of exogenous treatment on plant disease resistance and secondary metabolites. Usage 2 : 3-Bromo-2-fluoroaniline can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical pharmaceutical synthesis process. Production Method: With 2,6-dichloroisonicotinic acid as the starting material, 2,6-dichloroisonicotinic acid and phosphorus oxychloride are subjected to acid chloride reaction in the presence of a phase transfer catalyst to obtain 2,6-dichloropyridine-4- Carbonyl chloride, 2,6-dichloropyridine-4-carbonyl chloride and ammonia water undergo ammonolysis reaction to obtain 2,6-dichloroisonicotinamide, 2,6-dichloroisonicotinamide and sodium hypochlorite or sodium hypobromite in alkali 4-amino-2,6-dichloropyridine is obtained through the Hoffman rearrangement under the effect of. Toxicity Classification: Acute Toxicity: Flammability hazard characteristics: Storage and transportation characteristics:Store in a cool place. Keep container tightly closed and store in a dry and ventilated place. Fire extinguishing agent:Extinguish with water fog, alcohol resistant foam, dry chemical or carbon dioxide.
