Tridecanedioic acid

Tridecanedioic acid (CAS 505-52-2), also known commercially as brassylic acid, is a long-chain aliphatic dicarboxylic acid used as a monomer and functional ingredient across polymer, lubricant, and personal care manufacturing.

Its 13-carbon diacid structure makes it a sought-after building block where chain length directly influences end-product flexibility and performance. In polymer synthesis, it serves as a monomer for producing polyamides.

These polyesters offer enhanced flexibility and low-temperature performance, which is particularly relevant for specialty nylon grades and hot-melt adhesives. Lubricant formulators use it to produce diester base fluids.

These additive components are essential where thermal stability and film strength are required. In personal care, brassylic acid derivatives appear in emollient esters and conditioning agents targeted at skin and hair formulations.

Printing and packaging applications include its use in alkyd resin modification and ink binder systems requiring improved adhesion and substrate compatibility. This chemical is supplied as a white crystalline powder.

Standard commercial grades include technical and high-purity variants, with some suppliers offering material meeting polymer-grade specifications for monomer applications. Packaging typically ranges from kilogram-scale bags to bulk quantities.
