Application

关于水合肼对牙釉质样品的脱蛋白作用已有研究。它可作为以下过程的还原剂：
  • 制备银纳米颗粒。
  • 取代单硝基苯衍生物向相应苯胺的转化。
  • 与石墨一起用于硝基化合物(芳香族和脂肪族)到氨基化合物的转化。
水合肼可用于制备:
  • 通过与5-苄基-2-苯基色氨酸反应得到3-(2-苄基-6-羟基苯基)-5-苯基吡唑。
  • 通过与1,3-二苯基-2-丙烯-1- 1反应得到3,5-二苯基-2-吡唑啉衍生物。
  • 与3-芳基酰基-3,4-二氢喹啉-2(1H)-喹喔啉酮-反应生成3′- 1,2,3,4,4′,5′[喹诺沙林-2,5′ -吡唑]-喹喔啉酮-。
  • 它还可用于硝基芳香族胺的催化还原。

General description

在还原氧化石墨烯(RGO)对电极中加入水合肼可以改善其在染料敏化太阳能电池(DSSC)中的性能。

  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 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.

  4. 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. 

  5. What is the difference between Hydrazine hydrate product numbers 225819, 215155 and 207942?

    Prod. No. 215155 is anhydrous hydrazine. There is no water associated with this product. It has a molecular (formula) weight of 32.05. Prod. No. 207942 is hydrazine monohydrate. There is one mole of water for every mole of hydrazine. It has a molecular (formula) weight of 50.06. Prod. No. 225819 is hydrazine hydrate. The hydrazine content by weight from batch to batch may vary between 50 to 60%. Because the amount of water present (the other 40 to 50%) will also vary from batch to batch, it does not have a defined molecular (formula) weight. If a batch was found to contain 54 wt% hydrazine, then that batch would have 1.5 moles of water for every mole of hydrazine.

  6. Is Product 225819, Hydrazine hydrate, a liquid or a solid?

    The package sizes for this product are in a mass unit (gram) rather than a volume unit (mL). However, this product is a liquid and not a solid. It has a reported density of 1.029 g/mL at 25°C.

  7. My question is not addressed here, how can I contact Technical Service for assistance?
