Isooctane is a standard substance for testing the anti-knock performance of gasoline. The octane numbers of isooctane and heptane are specified as 100 and 0 respectively. If the anti-knock performance of a gasoline sample in a single- cylinder engine is equivalent to that of an isooctane-heptane mixture of a certain composition under specified test conditions, the octane number of the sample is equal to the volume percentage of isooctane in the standard fuel. Gasoline with good anti-knock performance has a high octane number. Brand: Soarwin CAS No.: 540-84-1 EC Number: 208-759-1 Molecular Formula: C8H18 Density: 0.692 g/mL at 25 °C(lit.)

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, and the commonly used esters are dibutyl sebacate and dioctyl sebacate. Sebacic acid plasticizers can be widely used in polyvinyl chloride, alkyd resins, polyester resins and Chemicalbook polyamide molding resins. Due to its low toxicity and high temperature resistance, it is often used in some special- purpose resins. Nylon molding resins produced with sebacic acid have higher toughness and lower hygroscopicity, and can also be processed into many special-purpose products. Sebacic acid is also a raw material for rubber softeners, surfactants, coatings and fragrances.
