Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

一般描述

二甲亚砜（DMSO）含有高极性和非极性基团，这使其具有两性分子特性。它可溶于水性和有机溶剂。它是疏水性药物制剂的常用溶剂，能有效清除羟基。[1][2]
这种物质被列入EU第10/2011号法规中用于与食品接触的塑料的正面清单。请点击此处查看列入10/2011 的所有化合物的参考物质。

应用

DMSO可用作气相色谱（GC）技术测定环境样品中分析物的分析参考标准品。[3]
有关合适仪器技术的更多信息，请参考产品分析证书。如需进一步支持，请联系技术服务。
葛根素可用作分子探用于通过高效液相色谱法（HPLC）检测葛根异黄酮给药后大鼠血浆中的葛根素浓度。[4]

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.
