一般說明

一氯化金是一种黄色结晶,单斜晶系结构。它在高温下会升华。三氯化金可高温分解为一氯化金。广泛用作金纳米颗粒和催化体系制备的前体。

應用

一氯化金用于:
  • 作为前体制备用于各种有机转化反应的磁性纳米催化系统。例如,Fe3O4@SiO2-P–AuCl可作为催化剂用于醛、酮和各种芳香胺的一锅还原胺化反应。[1]
  • 作为起始材料合成金络合物,用于药物递送、太阳能电池、传感器和有机合成领域。[2]
  • 作为预催化剂用于α-巯基联烯经由碳氢键形成的立体选择性环异构化为2,5-二氢噻吩。[3]
  • 作为催化剂用于烷氧硅基环己二烯经由金催化的环异构化作用转化为相应的1,2-和1,3-环己烯酮。[4]

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
