|Section7= }} Methoxyamine is the organic compound with the formula CH3ONH2. Also called ''O''-methylhydroxylamine, it a colourless volatile liquid that is soluble in polar organic solvents and in water. It is a derivative of hydroxylamine with the hydroxyl hydrogen replaced by a methyl group. Alternatively, it can be viewed as a derivative of methanol with the hydroxyl hydrogen replaced by an amino group. It is an isomer of N-methylhydroxylamine and aminomethanol. It decomposes in an exothermic reaction (-56 kJ/mol) to methane and azanone unless stored as a hydrochloride salt. ==Synthesis== Methoxyamine is prepared via ''O''-alkylation of hydroxylamine derivatives. For example, it is obtained by ''O''-methylation of acetone oxime followed by hydrolysis or the ''O''-methylated oxime:〔Review: Houben-Weyl, Methoden der organische Chemie, vol 10.1, p 1186.
