Dimethyl Sulfoxide (HPLC Grade), Fisher Chemical

Description

This HPLC-grade dimethyl sulfoxide (DMSO) from Fisher BioReagents is a high-purity solvent intended for demanding chromatographic separations. Supplied in a 4-liter container, it is formulated to meet the stringent purity requirements of high-performance liquid chromatography (HPLC). The solvent's chemical composition is C2H6OS, with a molecular weight of 78.13 g/mol and a CAS number of 67-68-5. Its high purity is critical for minimizing baseline noise and preventing ghost peaks that can interfere with sensitive analytical detection. As a polar aprotic solvent with excellent solvating power, it is frequently employed not only as a mobile phase component but also as a reaction medium in analytical chemistry workflows where solvent quality directly impacts data integrity.
