White flaky crystals, flammable. Melting point 134-134.4 ℃. Boiling point 294.5 ℃ (13.3kPa), relative density 1.2705. Refractive index 1.422. Molar combustion heat is 5.424MJ/mol. Slightly soluble in water, soluble in alcohol and ether.

It is mainly used as a raw material for sebacic acid ester plasticizers and nylon molding resins, and can also be used as a raw material for high-temperature resistant lubricants. Its main ester products are methyl ester, isopropyl ester, butyl ester, octyl ester, nonyl ester, and benzyl ester. The commonly used esters are dibutyl sebacate and dioctyl sebacate mash. Decaester plasticizers can be widely used in polyvinyl chloride, alkyd resins, polyester resins, and polyamide molding resins. Due to their low toxicity and high temperature resistance, they are often used in some special purpose resins. Nylon molding resin produced with sebacic acid has high toughness and low moisture absorption, and can also be processed into many special-purpose products. Sebacic acid is also a raw material for rubber softeners, surfactants, coatings, and fragrances.
