General description2,2,4-Trimethylpentane (TMP, Isooctane) is a saturated, branched hydrocarbon.[3] It has been reported to be nephrotoxic to male rats.[2] Density and viscosity of TMP at various temperatures (198K – 348K) and pressures (100MPa) has been evaluated.[3] It has been identified as nephrotoxicity inducing component in unleaded gasoline.
Application2,2,4-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.[1] It may be used to evaluate various physical properties (densities, viscosities, refractive indexes and surface tensions) of the binary mixtures of TMP and cyclohexane.
