 Copper dihydrazine sulfate (CAS NO.33271-65-7) is also named as Bis(hydrazine)bis(hydrogen sulfato)copper ; Caswell No. 237 ; Copper (cupric) dihydrazinium sulfate ; Copper dihydrazinium sulfate ; Copper, bis(hydrazine)bis(hydrogensulfato)- ; EPA Pesticide Chemical Code 050504 ; Mathieson 466 ; Omazene ; Omazine ; Cuprate(2-), bis(hydrazine-N)bis(sulfato(2-)-O)-, dihydrogen . Copper dihydrazine sulfate (CAS NO.33271-65-7) is toxic. It is flammable. It will produce copper, sulfur oxides and nitrogen oxides, acrid smoke by fire. So the storage environment should be ventilate, low-temperature and dry.
