Description
Pentadecanedioic acid (CAS 1460-18-0, EC 679-810-7), also referred to as DC-15 or pentadecanediacid, is a long-chain aliphatic dicarboxylic acid with the molecular formula C15H28O4. It carries no assigned E-code and is not classified as a food additive.
In polymer synthesis, DC-15 serves as a difunctional monomer that reacts with diamines or diols to build polyamide and polyester backbones, with the C15 chain length conferring flexibility and low-temperature performance. In lubricant formulations, it functions as a friction modifier and corrosion inhibitor by adsorbing onto metal surfaces through its carboxyl groups.
Pentadecanedioic acid is supplied as a crystalline powder at 97% minimum purity and is subject to REACH registration requirements for EU import and use. It is classified under HS code 2917.19.7050. Buyers should confirm grade specifications and available pack sizes directly with the supplier.
