This substance is produced through the iridium- or rhodium-catalyzed carbonylation of methanol in the Cativa and Monsanto processes. This compound's anhydride reacts with salicylic acid in the production of aspirin. Used industrially in the production of PVA polymers and as a polar protic solvent, this compound forms cyclic hydrogen-bonded dimers. Like lactic acid, it is produced when certain bacteria ferment ethanol. It forms ice-like crystals in its very pure "glacial" form. For 10 points, name this second-simplest carboxylic acid with formula CH3COOH, found in wine
