4-Amino-2-chloropyridine CAS NO.14432-12-3

Use: it is a plant growth regulator Forchlorfenuron intermediates. Used in medicine,pesticide, pigment intermediates.

Production method: it is prepared with isonicotinic acid as raw material, by chlorinationwith three phosphorus oxychloride, 2- Chloropyridine -4- carboxylic acid, and thenreacts with ammonia to generate the corresponding amide, followed by Hoffmandegradation reaction products. You can also use the 2- Chloropyridine -N- oxide as raw material, first with fuming nitric acid by nitration, reduction and iron powder andproducts in acetic acid.
