Allgemeine Beschreibung

The addition of hydrazine hydrate to reduced graphene oxide (RGO) counter electrode improves its performance in dye-sensitized solar cells (DSSC).[1]

Anwendung

Hydrazine hydrate has been used for the deproteination of the enamel samples in a study.[2] It may be used as a reducing agent in the following:
  • Preparation of silver nanoparticles.[3]
  • Transformation of monosubstituted nitrobenzene derivatives to the corresponding anilines.[4]
  • Along with graphite for the conversion of nitro compounds (aromatic and aliphatic) to the amino compounds.[5][6]
Hydrazine hydrate may be used to prepare:
  • 3-(2-Benzyloxy-6-hydroxyphenyl)-5-styrylpyrazoles by reacting with 5-benzyloxy-2-styrylchromones.[7]
  • 3,5-Diphenyl-2-pyrazoline derivatives by reacting with 1,3-diphenyl-2-propen-1-one.[8]
  • 3′-Aryl-1,2,3,4,4′,5′-hexahydrospiro[quinoxalin-2,5′-pyrazol]-3-ones by reacting with 3-arylacylidene-3,4-dihydroquinoxalin-2(1H)-ones.[9]
  • It may also be used in the catalytic reduction of nitroarenes to aromatic amines.[10]

Fragen

1-5 von 5 Fragen  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 Antwort

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 Antwort

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

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

    1 Antwort

    1. 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.

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

    1 Antwort

    1. 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.
