Sulfolane may be used as an analytical reference standard for the quantification of the analyte in groundwater samples using gas chromatography-mass spectrometry technique.
General description
Sulfolane is an aprotic polar solvent, used in the separation of aromatic hydrocarbons from aliphatic hydrocarbons.
Sulfolane is widely used in combination with diisopropanolamine in the sulfinol process of removal of toxic levels of hydrogen sulfide and carbonyl sulfide from raw natural gas condensate. It is also used as an industrial solvent for photographic chemicals, polymer, and petrochemical industries.

The supercharging effect of sulfolane on cytochrome c (cyt c) during electrospray ionization mass spectrometry (ESI-MS) in the absence of conformational effects was investigated. The addition of sulfolane on the order of 1 mM or greater to denaturing solutions of cyt

Boric acid inhibited the acid-catalyzed depolymerization of cellulose in sulfolane, a non-aqueous medium, at high temperature. Formation of the dehydration products such as levoglucosenone, furfural, and 5-hydroxymethyl furfural were also effectively inhibited. Similar inhibition was observed for cellooligosaccharides and starch
