Full Description

Sebacic acid (CAS 111-20-6) is a ten-carbon aliphatic dicarboxylic acid, C10H18O4, supplied as a polymer monomer and synthesis intermediate. It is a comonomer for nylon 6,10 and related polyamides, a raw material for alkyd and polyester resins, and a feedstock for plasticizer and lubricant esters. It also serves as a building block for corrosion-inhibitor chemistries.

Frequently Asked Questions

What is sebacic acid used for?

Sebacic acid (CAS 111-20-6; C10H18O4) is a ten-carbon aliphatic dicarboxylic acid supplied as a polymer monomer and synthesis intermediate. It is a comonomer for nylon 6,10 and long-chain polyamides, a raw material for alkyd and polyester resins, a precursor to sebacate plasticizer and lubricant esters, and a building block for corrosion-inhibitor chemistries.

What are the different grades of sebacic acid?

Sebacic acid is commonly offered in technical and higher-purity (e.g., refined or polymer/CP) grades distinguished by assay, color, and diacid impurity profile. This is a technical grade suited to resin, ester, and intermediate use. Confirm assay and specification against the CoA for your application.

Is sebacic acid water-soluble?

Sebacic acid has limited water solubility and is only slightly soluble in cold water, with solubility increasing in hot water; it is more soluble in alcohols and other polar organic solvents. It is supplied as a solid (typically flakes or powder). Confirm handling details against the SDS.

What is sebacic acid's role as a nylon 6,10 monomer?

Sebacic acid serves as the diacid comonomer that is condensed with hexamethylenediamine to produce nylon 6,10, a long-chain polyamide. Its ten-carbon chain length is what gives nylon 6,10 its characteristic lower moisture uptake and flexibility relative to shorter-chain nylons.

What is the HS code for sebacic acid and how is bulk quoted?

It is classified under HS 2917.13 (azelaic acid, sebacic acid, their salts and esters). As an industrial monomer it is quoted by grade and volume rather than at a fixed list price; submit a bulk RFQ with your target quantity and grade for a current quote, CoA, and SDS.
