1-Butyl-3-(4-sulfobutyl)imidazolium trifluoromethanesulfonate is a protic imidazolium ionic liquid, which is used as the electrolyte for polymer electrolyte membrane fuel cells (PEMFC) under anhydrous conditions [1]. 1-Butyl-3-(4-sulfobutyl)imidazolium trifluoromethanesulfonate has a good capacity for deep fuel desulfurization, and acts as an extracting solvent for aromatic sulfur and nitrogen compound extraction from aliphatic hydrocarbons [2]. 1-Butyl-3-(4-sulfobutyl)imidazolium trifluoromethanesulfonate can be used as a model compound for chemical analysis of ionic liquids by photoelectron spectroscopy)[3].
