Acetyl nitrate is the organic compound with the formula CH3C(O)ONO2.

It is classified as the mixed anhydride of nitric and acetic acids.

It is a colorless explosive liquid that fumes in moist air.

Alternatively, nitric acid adds to ketene.

[2] For aromatic nitrations, acetyl nitrate is generated in situ by mixing nitric acid with an excess of acetic anhydride in the presence of the aromatic substrate.
