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.

Aplicación
- Spectrophotometric Determination of Pharmaceuticals: Potassium permanganate is widely used in the spectrophotometric determination of pharmaceutical compounds. For example, it has been employed in the oxidative derivatization of beta-blockers such as atenolol and propranolol in alkaline medium, enabling the sensitive and accurate quantification of these drugs in pharmaceutical formulations. This method provides a rapid and cost-effective approach for pharmaceutical analysis (Vaikosen et al., Reviews in Analytical Chemistry, 2020).
- Environmental Monitoring: Potassium permanganate is used in environmental studies to oxidize and determine pollutants in water and soil samples. It is particularly effective in the oxidation of organic contaminants, facilitating their detection through various analytical techniques. Research has demonstrated the application of potassium permanganate in monitoring the oxidative degradation of ethanol in aqueous acidic media, highlighting its role in environmental analysis (Shimpi, International Journal of Science and Research, 2023).
- Food Preservation: Potassium permanganate is incorporated into packaging materials to extend the shelf life of perishable foods by scavenging ethylene, a ripening agent. Recent developments include the creation of low-density polyethylene-based multilayer films containing potassium permanganate and pumice, which effectively preserve the quality of avocados during storage. This application is crucial for reducing food waste and maintaining the quality of fresh produce (Wang and Ajji, Food Chemistry, 2023).

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
