Dimethyl dodecanedioate

Dimethyl dodecanedioate (CAS 1731-79-9), also known as dimethyl 1,12-dodecanedioate, is the methyl diester of dodecanedioic acid used as a reactive intermediate and functional additive across polymer and lubricant manufacturing.

It enables controlled chain-building in polyester and polyamide synthesis while also contributing lubricity in specialty formulations. In plastics and polymer production, it serves as a monomer for synthesizing long-chain polyesters.

These materials are ideal for applications where flexibility and low-temperature performance are required end-product targets. As a plasticizer, it is incorporated into polymer matrices to reduce brittleness in films and coatings.

It is also used in molded components without migrating as readily as shorter-chain alternatives. In lubricant formulations, its ester structure delivers boundary lubrication properties suited to metalworking fluids and synthetic base stocks.

The compound also functions as a chain extender or crosslinking precursor in specialty resin systems. This is particularly useful where precise molecular weight control is a formulation requirement for industrial chemical processes.

Dimethyl dodecanedioate is supplied as a liquid or low-melting solid depending on temperature conditions during handling and storage. It is available in technical grade for industrial polymer and lubricant applications.

Packaging typically ranges from drums to IBC containers, with bulk quantities available for high-volume manufacturing processes. Proper storage ensures the stability and performance of the chemical in various industrial settings.
