General description
Potassium acetate is a hygroscopic material used as a base in organic synthesis. It can also be used as a buffer and neutralizing agent.
Application
Potassium acetate can be used:
Potassium acetate can also be used as a base:
- As a catalyst in the glycolysis of rigid polyurethane (PU) using DEG (diethylene glycol) as a solvent.
- As a nucleophilic catalyst for addition and polymerization reaction.
- As a nucleophilic catalyst in the regioselective reaction of epoxides with S-phenyl thioesters.
- As a promoter/base in transition metal-catalyzed reactions.
- As a source of methyl radical in photo-decarboxylative nucleophilic additions to phthalimides and source of potassium ion for templating reactions.
Potassium acetate can also be used as a base:
- In the Lossen rearrangement of hydroxamic acid.
- In the E2 elimination′s reaction.
- In the fragmentation of α,α-dichloroketoesters and deprotonation of alcohols.

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

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
