一般描述

二甲基亚砜是一种两亲性分子,可溶于水和有机溶剂。这是一种常用的非质子溶剂 ,也作为有机合成试剂。

应用

DMSO已被用作制备化学发光试剂的培养基,该试剂可替代现有的用于免疫印迹技术的增强型化学发光试剂盒。

包装

100, 500 mL in glass bottle
1, 6×1, 2.5, 4 L in glass bottle
5, 10 L in poly drum
注: D5879-1L 为玻璃杯/D5879-1L-D 为塑料瓶。

生化/生理作用

DMSO是一种高极性的物质,可作为有机和无机化学品的工业溶剂。它也被用作冷藏活细胞的过程中的一种保护剂。它也有助于硫醇和二硫化物氧化成磺酸。

注意

容易过度冷却,并在室温下缓慢融化固化的产品放在室温下可以再次液化,对其本身无影响。

  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.
