Általános leírás

Gold(III) chloride trihydrate also known as chloroauric acid or auric chloride comes with orange colored crystals or crystal with chunks having a purity of >=99.9% based on trace metals analysis. Gold(III) chloride is a strong oxidizing agent and it finds applications in catalysis, nanotechnology, electroplating, medicine, surface chemistry, glass coloring etc.

Alkalmazás

Gold(III) chloride trihydrate is a chemical catalyst, often employed in the synthesis of organic compounds. It is used as a catalyst in oxidation reactions, such as the synthesis of vinyl ethers and esters.[1] Gold(III) chloride trihydrate can be used as a precursor for the synthesis of gold nanoparticles, which find applications in fields such as medicine (for targeted drug delivery and imaging), electronics (for conductive inks and sensors), and optics (for surface-enhanced Raman spectroscopy). [2,3] Gold(III) chloride trihydrate is also used in surface chemistry studies, particularly in the modification of surfaces for specific applications, such as in biosensors and fuel cells.

Tulajdonságok és előnyök

Questions

1–8 of 8 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.
      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

  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
