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.

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 difference between Product 520764, Palladium (II) acetate, and the palladium acetate in the form of a ChemDose® tablet?
1 answer-
The ChemDose® products offer a streamlined way to catalyze reactions. The catalyst is dispersed in an inert tablet matrix in specific millimolar and micromolar quantities. The tablets can decrease time spent on weighing/adding the catalyst to the reaction mixture. The tablets effectively give the same reaction yields with a controlled release of the catalyst. They are also extremely easy to remove after the reaction is complete. The inert tablet usually stays intact throughout the reaction. Product 684929 is the ChemDose® tablet that contains 2.0 μmol of palladium (II) acetate, while product#: 685593 is the 10μmol version. More information on these products can be found at the link below.

When using are Product 520764, Palladium (II) acetate, what can I use to remove traces of palladium that this catalyst may leave behind?
1 answer-
We would recommend using a metallic scavenger like the QuadraPureTM products. Product numbers 655422 and 657662 are designed to scavenge palladium ions and are effective in both acidic and basic conditions. The resins are capable of removing metallic contamination to very low levels and are ideal for pharmaceutical or fine chemical processing.
