N-Nitroiminoimidazolidine is a white crystalline powder chemical. Its chemical formula is C3H6N4O2 and the CAS NO is 5465-96-3. It is used as an intermediate of highly effective and low toxicity pesticide imidacloprid. It is prepared by cyclic synthesis of nitroguanidine and ethylenediamine to obtain N-Nitroiminoimidazolidine. Nitroguanidine and lye were added to the reactor, then ethylenediamine and 30% industrial hydrochloric acid were added at 0℃ to form a salt suspension, which was slowly hThe storageated to 60℃ for half an hour, and immediately transferred to the precooled reactor, where imidazolane was obtained through crystallization, centrifugal filtration and drying.

e container should be kept airtight and stored in a cool, dark place.
