Description

General description

1-Methyl-3-nitroguanidine (MNG) is formed as intermediate during the production of hydroxyl radical during 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) - induced gastric cancer in the xanthine oxidase system. MNG has been referred by the U.S. Air Force Armament Laboratory for use in explosive formulations. MNG is formed during nucleophilic attack by H₂O₂ on the nitroso nitrogen of MNNG. MNG is non-carcinogenic analog of N-methyl-N′-nitro-N-nitrosoguanidine (direct-acting carcinogen).

Application

1-Methyl-3-nitroguanidine (N-methyl-N′-nitroguanidine) was used in the synthesis of clothianidin hapten.
