Uses
Jeffrey Pine wood is similar to Ponderosa Pine wood, and is used for the same purposes. The exceptional purity of n-heptane distilled from Jeffrey Pine resin led to n-heptane being selected as the zero point on the octane rating scale of petrol.
As n-heptane is explosive when ignited, Jeffrey Pine resin cannot be used to make turpentine. Before Jeffrey Pine was distinguished from Ponderosa Pine as a distinct species in 1853, resin distillers operating in its range suffered a number of 'inexplicable' explosions during distillation, now known to have been caused by the unwitting use of Jeffrey Pine resin.
