CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | 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. |
