Triptane
# Triptane

Triptane, or 2,2,3-trimethylbutane, is an organic chemical compound with the molecular formula $C_7H_{16}$ or $(H_3C-)_3C-C(-CH_3)_2H.$ It is therefore an alkane, specifically the most compact and heavily branched of the heptane isomers, the only one with a butane $(C_4)$ backbone.

Triptane is commonly used as an anti-knock additive in aviation fuels.
