Isopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C 5 H 12 or CH(CH 3) 2 (C 2 H 5).. Isopentane is a volatile and flammable liquid. It is one of three structural isomers with the molecular formula C 5 H 12, the others being pentane (n-pentane) and neopentane (2,2-dimethylpropane).

Male mice of ICR strain were exposed to about 5% n-pentane for one hour while the oxygen in the environmental air was maintained at about 20%. Then their blood and liver tissue were collected and analyzed by means of GC and GC-MS. The metabolites thus obtained were 2-pentanol, 3-pentanol and 2-pentanone.The same procedure was repeated with isopentane; 3-methyl-2-butanol, 2-methyl-2-butanol and ...

Izopentanul (i-pentan, denumit și 2-metilbutan) este un compus organic cu formula moleculară C 5 H 12, fiind un izomer al pentanului (ceilalți izomeri sunt n-pentan și neopentan).Este adesea utilizat împreună cu azot lichid pentru a forma o baie lichidă cu o temperatură de −160 °C. Gazele naturale conțin de obicei 1% sau mai puțin izopentan, [5] dar compusul este un component ...

History. Although the mixture of pentanes was first isolated from the destructive distillation products of the boghead coal by Charles Greville Williams in 1862. [5] In 1864–1865 two chemists tried to extract same hydrocarbons from the Pennsylvanian oil. Carl Schorlemmer noted "that a mere trace of the liquid boiled below 30°C", [6] but the first to properly separate isomers (and thus ...
