Chemical Classes:Toxic Gases & Vapors -> Other Toxic Gases & Vapors
Canonical SMILES:CNN
Inhalation Risk:A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.
Effects of Short Term Exposure:The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system, liver and blood. This may result in liver impairment and the formation of methaemoglobin. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
Effects of Long Term Exposure:The substance may have effects on the liver and blood. This may result in liver impairment and the formation of methaemoglobin. This substance is possibly carcinogenic to humans.
Description Methyl hydrazine, CH3NHNH2, is a colorless, hygroscopic liquid with an ammonia-like odor. It is soluble in water, with a specific gravity of 0.87, which is lighter than water. Methyl hydrazine is toxic by inhalation and ingestion, and is a suspected human carcinogen. The TLV ceiling is 0.2 ppm in air, and the IDLH is 50 ppm. The target organs are the central nervous system, respiratory system, liver, blood, eyes, and cardiovascular system. The four-digit UN identification number is 1244. The NFPA 704 designation is health 4, flammability 3, and reactivity 2. The primary uses are as a missile propellant and a solvent.
Physical properties Fuming, clear, colorless liquid with an ammonia-like odor. Odor threshold concentrations ranged from 1 to 3 ppm (quoted, Keith and Walters, 1992).
Uses Methylhydrazine is used in missile propellants and as a solvent and chemical intermediate. Rocket fuel; solvent; chemical intermediate Missile propellant, intermediate, solvent.
