General description

Dimethyl sebacate (DMS) is a plasticizer that can be synthesized by esterification of sebacic acid.

Application

DMS can be used in the synthesis of decanedihydrazide which can be used as a precursor for isocyanates for the synthesis of thermoplastic polyurethanes. Transesterification of DMS with 2-ethylhexanol can be used to synthesize bis(2-ethylhexyl)sebacate for further use in petroleum based lubricants.
