Description
Methylnitronitrosoguanidine (MNNG) is an alkylating agent with toxic and mutagenic effects[1].
Characteristics
117
-0.79
N-methyl-n'-nitro-n-nitrosoguanidine appears as a yellow powder. Melting point 244°F. Decomposes above 212°F. A suspected carcinogen. Extremely hazardous as a mutagen. Avoid skin contact and inhalation of of vapors. Usually stored frozen (below 32°F) in polyethylene bottles that are tightly closed and contained in a metal can. May decomposed during prolonged storage and develop sufficient pressure in a closed container to explode. Keep away from heat, sparks, and open flame.
