Aplicação

O cloreto de ouro (III) tri-hidratado pode ser usado como um sal precursor de ouro para a produção de nanopartículas de ouro (AuNP) usando vários agentes redutores.[1][2]
Ele também pode ser usado como catalisador nos seguintes processos:
  • O HAuCl4 3H2O inPEG 400 é usado para sintetizar derivados de espirocromeno por meio de uma reação de três componentes em um único pote de isatinas/acenaftoquinona, compostos de metileno ativo e 1,3-dicetonas cíclicas/4-hidroxicumarina.[3]      
  • O sistema catalítico Au/CeO2 é usado na oxidação quimiosseletiva de álcoois aromáticos/alifáticos em compostos carbonílicos correspondentes.[4]      
  • Usado na síntese de alilnaftalenos por abertura de anel de 1,4-epoxi-1,4-diidronaftalenos com aliltrimetilsilano.[5]

Questions

1–5 of 5 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. What is the density of the gold chloride trihydrate G4022?

    1 answer
    1. This product may have a physical form ranging from powder to crystals or chunks. The density is not determined. The bulk density of solid materials is highly variable and depends not only on batch variation but also on differences in handling and transportation.

  4. What is the shelf life of gold chloride G4022 in solution?

    1 answer
    1. The recommended storage temperature for a powder product may not be the same as that for the reconstituted solution. However, for Gold Chloride, there are gold chloride solutions available with a recommended storage temperature of 2-8°C. Therefore, storing the solution at 2-8°C is advisable. Generally, the stability of the solution should be around 18 months or potentially longer. It's important to note that this may not always apply to other products.

    Storage conditions for gold chloride trihydrate solution

    We need to know if storing gold chloride trihydrate solution at -20°C or -80°C is advisable or not? Thanks

    Helpful?

    1. Response from MilliporeSigma:

      The stability of this product in solution has not been determined. In this case, we recommend preparing solutions fresh.
      According to literature solutions could be stable at -80°C for 6 months, or -20°C for 1 month. Stability will need to be tested by the end user.
      We encourage customers who experience problems with our products to contact us for additional technical support. Please visit https://www.sigmaaldrich.com/US/en/support/customer-support to submit a Product Technical Inquiry.
