Chemistry is traditionally divided into organic and inorganic chemistry. Safety of 6-Chloro-4-iodo-3-methoxypyridazine, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 181355-92-0
Metalation of diazines XVII. Very hindered bases as new metalating agents, improvement of regioselectivity for the metalation of 3-chloro-6-methoxypyridazine
The different factors governing the regioselectivity of the metalation of 3-chloro-6-methoxypyridazine with alkylamides were studied. Very hindered bases were used as new metalating agents and a very good regioselectivity was obtained.
