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 in polymer, lubricant and personal care manufacturing.

Where is Tridecanedioic acid used?

• Polymer synthesis: monomer for polyamides and polyesters offering flexibility and low-temperature performance for specialty nylon grades and hot-melt adhesives
• Lubricants: diester base fluids and additive components for thermal stability and film strength
• Personal care: emollient esters and conditioning agents for skin and hair formulations
• Printing and packaging: alkyd resin modification and ink binder systems for adhesion and substrate compatibility
• Its 13-carbon diacid structure makes it a building block where chain length influences end-product flexibility and performance.

Commercial specifications

• Standard commercial grades include technical and high-purity variants; some suppliers offer polymer-grade specifications for monomer applications
• Packaging typically ranges from kilogram-scale bags to bulk quantities
