What is the molarity of Product D5879, Dimethyl sulfoxide?
Pure solvents do not technically have a molarity (defined as moles of solute per liter of solution), since there is no solute distinct from the pure material. However, an effective molar concentration of 14.1M can be determined for this product, based on a density of 1.1 g/mL and a molecular weight of 78.13 g/mol.
The Dimethyl sulfoxide, Product D5879, I ordered arrived as a solid. Is the product still acceptable?
Sigma-Aldrich ships many products, including DMSO, at ambient temperature. As a result product D5879 might arrive as a solid depending on the weather conditions during shipment. The melting point of DMSO is 16-19°C. Therefore, if the solid is allowed to warm to room temperature, it will melt without any impact on the quality of the product.
My application requires a dry solvent. How can I remove water that is present in Dimethyl sulfoxide, Product D5879?
This product has a water content specification of not more than 0.1%, which may be low enough for your application. Other DMSO products may have more water present. Molecular sieves are typically zeolite compounds that strongly adsorb water and have carefully controlled pore sizes. If you would like, dried sieves may be placed into the bulk solvent container (about 5%-10% by volume) to remove most water. Sigma-Aldrich offers 4 Å molecular sieves (e.g. product 334308), which would be effective in removing residual water from DMSO.
