-(C=O)-O-(C=O)H. It can be viewed as the mixed anhydride of acetic acid (H3C-(C=O)OH) and formic acid (H(C=O)OH) by removal of a molecule of water.

It can be produced by reaction between sodium formate and acetyl chloride in anhydrous diethyl ether, at 23–27 °C.[2] Among other uses, it is a formylation agent for amines, amino acids, and alcohols, and a starting material for formyl fluoride.[2]
