Dimethyl dodecanedioate

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

Where is Dimethyl dodecanedioate used?

• Polyester and polyamide synthesis: controlled chain-building and lubricity in specialty formulations
• Plastics and polymers: monomer for long-chain polyesters
• Plasticizer in polymer matrices: reduces brittleness in films and coatings
• Molded components: less migration than shorter-chain alternatives
• Lubricants: boundary lubrication in metalworking fluids and synthetic base stocks
• Specialty resins: chain extender or crosslinking precursor
• It serves as a monomer for synthesizing long-chain polyesters.

Good to know: Used where flexibility and low-temperature performance are end-product targets, and where precise molecular weight control is a formulation requirement.

Commercial specifications

• Packaging from drums to IBC containers, with bulk quantities for high-volume manufacturing
