tert-Butyl methyl ether (Cat No.: R022709) is a volatile, colorless organic compound with the chemical formula C₅H₁₂O. It is an ether consisting of a tert-butyl group and a methyl group bonded to an oxygen atom. MTBE is widely used as a fuel additive to increase octane ratings and reduce engine knocking. It improves combustion efficiency and reduces emissions in gasoline. Though effective, its environmental persistence and water solubility have raised concerns about groundwater contamination, leading to reduced usage in some regions.
