一般描述

二甲基亚砜(DMSO)是一种有效的非质子溶剂，无色、无味，且天然具有吸湿性。DMSO可增强各种亲水和亲脂性通透剂的通透性。它是广泛使用的实验室溶剂之一。

应用

二甲基亚砜(DMSO)用作各种实验研究的化合物检测工具。在淀粉样蛋白ββ聚集实验方案中，它可作为溶剂重新溶解多肽以维持其解离状态。

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. What type of filter is used to sterile-filter Dimethyl sulfoxide (DMSO)?

    DMSO can be sterile-filtered through a 0.2 micron PTFE filter. The sterility testing is per the current US Pharmacopoeia method.

  8. 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.

  9. 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.

  10. What is Sure/Seal™ packaging?

    The Aldrich Sure/Seal™ packaging system is useful in the handling and storage of air-sensitive reagents.

  11. Is Dimethyl sulfoxide a sterile product?

    No, this product is not considered sterile.  Product Nos. D2560 and D2438 are sterile-filtered.

  12. 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.
