2,2,4-Trimethylpentane(Cat No.: R034082), commonly known as isooctane, is a branched-chain alkane with high volatility and excellent combustion properties. It serves as a standard reference fuel with an octane rating of 100, making it critical in evaluating engine knocking resistance in internal combustion engines. Its chemical stability and low reactivity also make it useful as a non-polar solvent in laboratories. Isooctane is colorless and flammable, primarily used in fuel formulations, petrochemical research, and testing gasoline performance. For industrial and laboratory use only.
