Applicazioni

2,2,4-Trimethylpentane is used as a solvent in spectrophotometric analysis and in organic synthesis. Due to its high antiknock octane number, it is widely employed as a standard reference fuel for octane ratings. It acts as an entrainer in azeotropic distillation as well as thinner. It is involved as processing aids in the petroleum industry.

Note

Keep container tightly closed in a dry and well-ventilated place. Keep away from sources of ignition. Incompatible with strong oxidizing agents.
