2-Butyloctanedioic Acid
2-Butyloctanedioic Acid (CAS: 50905-10-7) is a branched dibasic acid supplied as a white waxy solid. The two carboxylic acid groups react readily with diols and diamines, while the butyl branch interrupts chain packing and introduces internal flexibility, which is useful when a softer or more soluble polyester is wanted. It is mainly used as a specialty monomer and intermediate for polyesters, polyamides, ester lubricants and plasticiser chemistry, where it improves low-temperature behaviour. Purity is controlled at 98% with low monoacid content to keep polymerisation reproducible.
• Polymer intermediates: used in polyester, polyamide and specialty resin synthesis where chain branching is required.
• Lubricant esters: a precursor for synthetic ester basestocks with good low-temperature performance.
• Plasticiser chemistry: applied in the development of specialty ester plasticisers and coalescing agents.
• Fine chemical synthesis: serves as a diacid building block for coatings, adhesives and surface-active esters.
