The preparation method of 4-Amino-2-Chloropyridine CAS 14432-12-3 Intermediates CAS 14432-12-3 is to use isonicotinic acid as raw material and chlorine it with phosphorus oxychloride to obtain 2-chloropyridine-4-carboxylic acid. Then it reacts with ammonia gas to generate the corresponding amide, and then performs Hofmann degradation reaction to obtain the product. It is also possible to use 2-chloropyridine-N-oxide as a raw material, first nitrate with fuming nitric acid, and then reduce it with iron powder in acetic acid to obtain the product.
1. 4-Amino-2-Chloropyridine CAS 14432-12-3 belongs to the active plant regulator of cytokines, which can promote cell growth and differentiation, prevent plant aging, promote slim formation and fruit hypertrophy.
2. 4-Amino-2-Chloropyridine CAS 14432-12-3 Apis and Intermediates is a new class of highly active, low-toxicity, broad-spectrum plant growth regulator. It has cell division activity, and its mechanism of action is the same as that of yin-type cytokinins (kinetin, zeatin), but its activity is 10 to 100 times higher than them
3. 4-Amino-2-Chloropyridine with the CAS number 14432-12-3 is a chemical compound with applications in the field of organic synthesis and pharmaceuticals. 4-Amino-2-Chloropyridine CAS 14432-12-3 4-Amino-2-Chloropyridine CAS 14432-12-3 Apis and Intermediates can be used in Pharmaceutical Intermediates, Agrochemicals, Chemical Research.
