Descrizione generale

La soluzione di idrossilammina è impiegata diffusamente in sintesi organica, nell'industria dei polimeri e nel trattamento delle acque come agente riducente e antiossidante.[1]

Applicazioni

La soluzione di idrossilamina (NH2OH) può essere usata come reagente per la preparazione di:
  • Amidi primarie da aldeidi catalizzate da un complesso arene-rutenio(II).[2]
  • Idrossiaminoguanidine e derivati carbossamidici dell′ofloxacina per studi biologici.[3][4]
  • Nanoparticelle di Fe3O4/Au (GoldMag) per l′immobilizzazione degli anticorpi.[5]

Reagente per la preparazione di:
  • Profarmaco per l′agente cardiovascolare Nω-idrossi-L-arginina (NOHA, precursore del monossido di azoto)
  • Idrossiaminoguanidine in qualità di agenti anticancro
  • Agonisti del recettore del glucocorticoide non steroideo 2,3-diidrochinolina con ridotta transattivazione della fosfoenolpiruvato carbossichinasi (PEPCK)
  • Derivati carbossiamidici dell′ofloxacina con migliorate proprietà antibiotiche
  • Inibitori dell′enzima di conversione del TNF-α (TACE) basati sugli analoghi della coumarina
  • Inibitori dell′integrasi dell′HIV

Questions

1–3 of 3 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    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.

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

    1 answer
    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

  3. Please provide the molarity for Product 467804?

    1 answer
    1. The molarity of a 50% solution for Product 467804 would be 15.1M. This is calculated based on the fact that 1M is equivalent to 33.03 g in 1L
