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.

General description
Application
- A polymerization initiator in the synthesis of polyacrylamide via radical polymerization of acrylamide.
- An oxidizing agent in the photochemical oxidation of atrazine aqueous solution.
K2S2O8 can also be used in the following process:
- K2S2O8-AgSCF3 catalytic system is used in the direct trifluoromethylthiolation of unactivated C(sp3)-H bonds under mild conditions. Usage of K2S2O8 in this process plays an important role in the activation of the C-H bond and the oxidation of AgSCF3.
- K2S2O8-FeCl3 is used for the thiocyanation of 2H-indazoles using ammonium thiocyanate as a thiocyanating agent.

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