Descrição geral

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 identified as nephrotoxicity inducing component in unleaded gasoline.

Aplicação

2,2,4-Trimethylpentane (TMP, isooctane) may be used to evaluate various physical properties (densities, viscosities, refractive indexes and surface tensions) of the binary mixtures of TMP and cyclohexane.

B G Short et al.
Toxicologic pathology, 14(2), 194-203 (1986-01-01)
Unleaded gasoline causes acute and chronic nephrotoxicity and renal tumors in male rats, but not female rats or mice of either sex. An active nephrotoxic component of unleaded gasoline has been identified as 2,2,4-trimethylpentane (TMP). The first objective of this
E A Lock et al.
Toxicology and applied pharmacology, 91(2), 182-192 (1987-11-01)
Trimethylpentane (TMP) produces nephrotoxicity in male but not in female rats. The toxicity is characterized by an increase in protein droplets in proximal convoluted tubular cells and an increase in the renal concentration of the male-rat-specific protein alpha 2u-globulin. Subcellular
