Dioctyl maleate is a chemical compound with the molecular formula C20H36O4. It is often called DOM in the chemical industry even though the octyl is not straight chained but branched. It is manufactured by reacting 2-ethylhexanol with maleic anhydride and an esterification catalyst. This is a key intermediate raw material in the production of DOSS surfactants[2], including the pharmaceutical drug docusate (dioctyl sodium sulfosuccinate).[3]. The DOSS molecule is formed by reacting a metal (usually sodium) bisulfite across the vinylic double bond of the dioctyl maleate thus forming an ionic species.
