Description
Dimethyl dodecanedioate (CAS 1731-79-9) is a dicarboxylic acid diester also referenced as DDME, DMD 2, and NSC 118878. It carries no assigned E-code. The compound belongs to the long-chain ester family and is classified under HS code 2917.19.7050.
In polymer and coating formulations, DDME functions as a plasticizer by intercalating between polymer chains, reducing glass transition temperature and improving flexibility. In lubricant blends, its ester backbone provides film-forming properties that reduce metal-to-metal friction. Personal care formulators use it as a carrier solvent to improve spreadability and active ingredient delivery.
Dimethyl dodecanedioate is supplied in solid and liquid forms depending on ambient temperature, with grades available for industrial and specialty applications. The substance is registered under REACH and must be handled in accordance with applicable EU chemical regulations. Packaging formats typically include drums and IBCs for bulk procurement.
