Description
Dodecanedioic acid (CAS 693-23-2), also known as DDA or Corfree M2, is a 12-carbon dicarboxylic acid supplied as a white crystalline powder. It carries no assigned E-code and is referenced under synonyms including SL-AH and NSC 400242. It falls within the organic acids category under HS code 29171990.
In polyamide and polyester synthesis, DDA acts as a difunctional monomer, forming ester or amide linkages that extend polymer chain length and influence melt behaviour. In metalworking fluids and personal care emulsions, its balanced hydrophilic-lipophilic structure enables stable oil-in-water dispersion and provides a measurable lubricity contribution at the substrate surface.
DDA is available in powder and pellet form, with grades conforming to REACH registration requirements for EU supply. Procurement teams should confirm whether food-contact or cosmetic-grade specifications are required, as FCC and Ph.Eur. aligned certificates of analysis can be requested from qualified suppliers.
