Chemical properties It is an organic chemical compound made up from a methyl group (-CH3) and nitroso group (-NO). At room temperature, it is a flammable gas that boils at -18.3 °C (±9.0 °C).CSID:63264, https://www.chemspider.com/Chemical-Structure.63264.html, (accessed 16:05, Mar 6, 2026)
Synthesis Same as trifluoronitrosomethane (a rather rare example of a blue gas), it can be synthesized by the reaction of nitric oxide with methyl iodide with a catalytic amount of mercury metal:
2 CH3I + 2 NO → 2 CH3NO + I2
