introduction	2-amino -6-chloropyridine is orange or bright yellow solid at normal temperature and pressure, which has good solubility in strong polar solvents, but not good solubility in water. It can be used as an intermediate in organic synthesis.
Uses	2-amino-6-chloropyridine is used as an intermediate in the organic synthesis of heterocyclic compounds. Its uses include the use of chlorine atoms on the ring for Suzuki coupling or related functional group conversion reactions; in addition, under specific bromination conditions, 2-Amino-6-chloropyridine can introduce a bromine atom at the para position of the amino group with high regioselectivity.
Synthesis method	For the synthesis of 2-amino-6-chloropyridine, the conventional synthesis method is from 2-chloro-6-nitropyridine Starting from, after the reduction reaction of sodium borohydride in an alcohol solvent, the target product of the reduction of nitro to amino group is obtained.
