Answer:The product is specified at ≥99.7% purity.
Answer:It is suitable for HPLC applications.
Answer:This configuration contains 100 mL.
Dimethyl sulfoxide is used as a high-purity polar aprotic solvent for analytical laboratory workflows, including HPLC sample preparation and chromatographic methods. This Sigma-Aldrich grade is suitable for HPLC and has a stated purity of at least 99.7%. DMSO dissolves a wide range of polar and nonpolar compounds and is miscible with water, making it useful when analytes have limited solubility in more conventional aqueous or organic mobile-phase components. This configuration contains 100 mL. The defined analytical grade helps reduce background impurities in sensitive chromatographic work. Because DMSO has a relatively high boiling point and strong solvating power, methods should account for its physical properties and compatibility with the analytical system. The product is intended for controlled laboratory use where solvent quality and reproducibility are important.
