詳細

酸化重水素、重水素化溶媒は、NMR(核磁気共鳴)解析のための標準純度溶媒です。液体の酸化重水素の様々な熱力学特性(分子間振動周波数、水素結合エネルギー、自由エネルギー、エンタルピーおよびエントロピー)が、測定されています。D2Oの電離定数(5~50°C)、pK値(25°C)およびエンタルピー、エントロピー、熱容量変化(D2Oの解離)が報告されています。

アプリケーション

酸化重水素は以下のことに使用できます:
  • トリフルオロ酢酸無水物との反応によるトリフルオロ酢酸-dの調製。
  • ルテニウム触媒存在下でのH/D交換反応を介したβ-炭素位における一級および二級アルコールのための重水素化試薬。
  • パラジウム錯体存在下、(E)-1,2-二重水素化アルケンの生成のための、アルキンへの重水素転移試薬としてヘキサメチルジシランとの併用。

酸化重水素(重水、水-d2、D2O)は、NMRによる定量実験における、内部標準とサンプルを溶解するための溶媒として使用されています。トリス(2,2′-ビピリジル)ジクロロルテニウム(II)十水和物 Ru(bpy)3の溶解に使用されています。4

試験成績書(COA)

原産地証明書(COO)

  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 should I store Product 151882, Deuterium oxide, to preserve its purity?

    According to our MSDS, deuterium oxide is classified as hygroscopic and should be stored under an inert gas like nitrogen, to prevent hydrogenated water uptake.

  4. I don't have the ability to store Product 151882, Deuterium oxide, under nitrogen to prevent H2O uptake. Is there another way that I can work with D20 in order to preserve its purity?

    You may be interested in our ampulized deuterium oxide products: 521965 (10x0.6mL), 441376 (10x0.75mL) or 269794 (10x1mL). These products are ideal for one time use applications, like as an NMR solvent, because there is decreased chance of water uptake during storage.

  5. 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.

  6. 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.

Robust methods for differentiating long-lived nanobubbles from other nanoparticles are required. Evaluation of the density and compressibility of nanoparticles should enable nanobubbles to be differentiated from other nanoparticles, although the response of nanobubbles to pressure can be strongly influenced by
