一般描述

二甲基亚砜是一种有机硫化合物，常用作极性溶剂，能溶解广泛的极性和非极性化合物。它还可用作几种熟知反应的反应试剂，包括Swern氧化、2a Pfitzner-Moffatt氧化和2b Corey-Chaykovsky反应。

应用

二甲基亚砜（DMSO）已用于：
  • 制备乙基4-[18F]氟苯甲酸酯。
  • 作为3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴化物（MTT）试验的培养基。
  • 作为化学合成中的溶剂。
  • 溶解和制备小分子、药物和化学化合物的储备溶液，以用于各种检测和实验。

注意

在室温下容易过冷并缓慢重融。 固化产品可以通过加热至室温来重新液化，而不会损害产品。

  1. What is the molarity of DMSO?

    DMSO will have a molarity of 14.1M, based on a density of 1.1 g/mL and a molecular weight of 78.13 g/mol.

  2. What is the DMSO dissolved in?

    DMSO is not dissolved in any solvent. It is a pure chemical compound that is a liquid at room temperature.

  3. Where does DMSO come from?

    DMSO is known to have been isolated from tree bark in the past. It is now a commericially synthesized solvent.

  4. Does DMSO have any synthetic utility?

    DMSO has been used to oxidize thiols and disulfides to sulfonic acids, hydrolysis of epoxides, thioalkylation of phenols, and oxidation of primary alcohols and halides, and esters of primary alcohols to aldehydes.

  5. 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.

  6. Dimethyl sulfoxide (DMSO) should be a liquid.  Why did it arrive as a solid?

    DMSO supercools easily, and re-melts slowly at room temperature. The melting point is 16-19 °C. The solidified product can be re-liquefied by warming to room temperature without detriment to the product.

  7. 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.

  8. 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.
