Undecanedioic acid

Undecanedioic acid (CAS 1852-04-6), also known as hendecanedioic acid, is an eleven-carbon aliphatic dicarboxylic acid; a bifunctional building block for polymer chemistry and industrial formulation.

Where is Undecanedioic acid used?

• Polymer chemistry: monomer for specialty polyamides, polyesters and ester-based intermediates
• Coatings and adhesives: chain extender or crosslinker in polyester and polyamide resin systems
• Lubricants: diester and complex ester base fluids for metalworking and industrial oils
• Personal care: ester derivatives in emollients and rheology modifiers
• Sealants and elastomers: reactive intermediate that adjusts chain length and mechanical properties in cured polymer networks

Commercial specifications

• Technical grade: purity typically 98% or higher
• High-purity grades for specialty polymer and personal care applications
