Very volatile yellow liquid.

Water soluble but relatively unstable in water .

ACUTE/CHRONIC HAZARDS: Methylvinylnitrosamine is highly toxic by ingestion and inhalation. When heated to decomposition, Methylvinylnitrosamine emits toxic fumes of NOx.

Flash point data for Methylvinylnitrosamine are not available; however Methylvinylnitrosamine is probably combustible.

This chemical is not manufactured but occurs as a chemical reaction byproduct found in the dye, automotive, rubber, and leather industries.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required

Light sensitive. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials strong bases, strong acids, oxoacids, epoxides. A nitrated amine. Amines are combustible. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

N-Nitrosomethylvinylamine is a yellow liquid.

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.

N-Methyl-N-nitroso-ethenamine is used as research reagent for base induced fragmentation to give aldehydes or ketones and smaller alkylnitrosamine

N-nitrosomethylvinylamine is used as a research chemical; no other uses were identified (IARC 1978, HSDB 2009).

ChEBI: N-Nitrosomethylvinylamine is a nitroso compound.

NMVA has not been produced commercially and is currently produced in limited quantities for research purposes. There are no reports that it occurs in the environment and exposure is likely limited to researchers using NMVA.

N-Nitrosomethylvinylamine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
