一般描述

该产品为30%的过氧化氢水溶液。过氧化氢更常用作绿色氧化剂。由于它具有高活性氧含量,并且副产物是水,因此它是其他氧化剂的更好替代品。 本产品是符合USP(美国药典)测试规范的高质量药典产品。它可以用于科研和试验研究。

应用

过氧化氢溶液已用于:
  • 制备消毒剂溶液以及用于骨同种异体移植的新型洗涤过程的过乙酸。
  • 与3,3′,5,5′-四甲基联苯胺二盐酸盐(TMB)组合以制备辣根过氧化物酶(HRP)-缀合的金纳米颗粒(GNP)。
  • 用于在神经元表达的NeuN(可溶性核蛋白)的免疫染色。

  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. What's the molarity of Product H3410, Hydrogen Peroxide Concentrate (H2O2) as sold?

    If we assume an H2O2 concentration of 30% (w/w) and a density of 1.11 g/mL, then the approximate molarity is 9.8 M. You may use the exact concentration of the lot to calculate molarity more precisely. This product is 29.0% to 32.0 % (w/w).

  4. I heard that there is a way to calculate the concentration of Product H3410, Hydrogen Peroxide Concentrate (H2O2) with a spectrophotometer.  How do I do this?

    You can use the molar extinction coefficient of H2O2, which is 43.6 M-1cm-1at 240 nm.  Using the Beer-Lambert Law, A = ebc where e = the molar extinction coefficient, b = the path length of the cuvette in cm, and c = molar concentration, you can solve for "c" based on the absorbance you get for a H2O2 solution. If you dilute your solution with a solvent to get an absorbance reading within the capabilities of your spectrophotometer, include the dilution factor in your calculations, and correct your absorbance reading with any absorbance reading contributed by the solvent itself.

  5. My bottle of Hydrogen Peroxide always arrives leaking.  Why is this?

    According to US Department of Transportation (DOT) regulations, concentrated hydrogen peroxide must be shipped in bottles with vented caps.  This is because H2O2 disproportionates to H2O and O2 which can cause pressure buildup.  Because the bottles have vented caps, we cannot guarantee that there will be no leakage.  The only way to obtain hydrogen peroxide with a sealed cap is to purchase the 3% solution (e.g., Product No. 323381).

  6. How do I find price and availability?
