Application

El DMSO se ha utilizado como medio para preparar un reactivo quimioluminiscente que pueda ser un sustituto para los kits de quimioluminiscencia mejorada comercializados para la técnica de inmunotransferencia.

Biochem/physiol Actions

El DMSO es una sustancia muy popular que puede utilizarse como un disolvente industrial para compuestos químicos orgánicos e inorgánicos. También se utiliza como protector durante la conservación en frío de las células vivas. Es útil también para la oxidación de tioles y disulfuros a ácidos sulfónicos.

Disclaimer

Fácilmente superenfriado, vuelve a fundir lentamente a temperatura ambiente. Producto solidificado que puede volver a licuarse por calentamiento a temperatura ambiente sin detrimento del producto.

General description

El dimetilsulfóxido es una molécula anfipática, soluble tanto en disolventes acuosos como en disolventes orgánicos. Se utiliza normalmente como disolvente aprótico y también como reactivo en síntesis orgánicas.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. 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.

  6. 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.

  7. 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.
