CHEMICAL AND PHYSICAL PROPERTIES

Physical Description N-nitroso-n-methylurethane is a solid.
Color/Form Yellow to pink oil
Odor Sweet smelling
Boiling Point BP: 62-64 °C at 12 mm Hg; 70 °C at 27 mm Hg
Solubility Soluble in many common organic solvents
Density 1.133 at 20 °C/4 °C
Vapor Pressure 1.18 [mmHg]
Stability/Shelf Life Unstable. It is sensitive to light, and some photodecomposition products have been described. Spontaneous decomposition may occur, especially on heating. Stability in aqueous solutions is pH-dependent. At alkaline pH, it decomposes to dizomethane, which can also act as an alkylating agent. At 20 °C the following half-lives in hours at various pH values have been reported: 120 at pH 6.0; 80 at pH 7.0; 17.5 at pH 8.0; and 0.9 at pH 9.0 ... Extremely volatile.
Decomposition When heated to decomposition it emits toxic fumes of /nitrogen oxides/.
Viscosity Low
Refractive Index Index of refraction: 1.43632 at 20 °C/D
Other Experimental Properties When heated to decomposition it emits toxic fumes of NOx
Chemical Classes Nitrogen Compounds -> Nitrosamines
