Triptane Explained

Triptane, or 2,2,3-trimethylbutane, is an organic chemical compound with the molecular formula C7H16 or (H3C-)3C-C(-CH3)2H. It is therefore an alkane, specifically the most compact and heavily branched of the heptane isomers, the only one with a butane (C4) backbone.

Due to its high octane rating (112.8 RON, 101.3 MON[1]) triptane has been produced on alkylation units since 1943[2] for use as an anti-knock additive in gasoline.
