Triazane is an

inorganic compound In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemis ...

Compounds containing the triazane skeleton

Several compounds containing the triazane skeleton are known, including 1-methyl-1-nitrosohydrazine (), produced from the solventless reaction of methylhydrazine () and an

alkyl nitrite In organic chemistry, alkyl nitrites are a group of organic compounds based upon the molecular structure , where R represents an alkyl group. Formally they are alkyl esters of nitrous acid. They are distinct from nitro compounds (). The first ...
