    2,2,4-Trimethylpentane (TMP, Isooctane) is a saturated, branched hydrocarbon. It has been reported to be nephrotoxic to male rats. Density and viscosity of TMP at various temperatures (198K - 348K) and pressures (100MPa) has been evaluated. It has been indentified as nephrotoxicity inducing component in unleaded gasoline.

    Application

    2,2,4-Trimethylpentane (TMP, Isooctane) has been used for the isolation of mercury species during the HPLC cold vapor atomic fluorescence spectrometric (HPLC-CVAFS) quantification of MeHg in various biological samples. It may be used to evaluate various physical properties (densities, viscosities, refractive indexes and surface tensions) of the binary mixtures of TMP and cyclohexane.
