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.

Application
It can also be used as a catalyst in the following processes:
- HAuCl4 3H2O inPEG 400 is used to synthesize spirochromene derivatives via a one-pot three-component reaction of isatins/acenaphthoquinone, active methylene compounds, and cyclic 1,3-diketones/4-hydroxycoumarin.[3]
- Au/CeO2 catalytic system is used in chemoselective oxidation of aromatic/aliphatic alcohols to corresponding carbonyl compounds.[4]

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

What is the density of the gold chloride trihydrate G4022?
1 answer-
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.

What is the shelf life of gold chloride G4022 in solution?
1 answer-
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.
