Pyridazine Chemical Properties,Uses,Production

Heterocyclic compound

Pyridazine refers to a heterocyclic azine compound containing a nitrogen hexaheterocyclic , it and pyrimidine, pyrazine are isomers of each other , it is insoluble in petroleum ether, soluble in methanol, ethanol and ether, and it can be miscible with water, benzene and dimethyl formamide immiscibility. Pyridazine is a weak base, which can form salts with picric acid, and hydrochloric acid; pyridazine is not prone to nucleophilic and electrophilic aromatic substitution reaction; it is stable to potassium permanganate; sodium or alcohols may be reduced open-chain , and converted to 1,4-diaminobutane. Pyridazine is widely used as pharmaceutical raw materials, such as long-term sulfa SMP which is pyridazine derivative, 4-amino-cinnoline which belongs to antimalarials, blood pressure drug hydralazine, etc. all use pyridazine as raw materials; it can also be used as raw material of pesticides, for the production of herbicides, "herbicide-sensitive", "Milstem", "bromine herbicide-sensitive", "Kusakira," "maleic hydrazide", "Norflurazon", "pyridate "" insecticide "," imputed phosphorus "and so on.
