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
- Iridium-based double perovskites for efficient water oxidation in acid media: This study highlights the development of iridium-based double perovskites that reduce iridium content while maintaining high activity and stability for water oxidation, significant for energy-related applications in material science (Diaz-Morales et al., 2016).
- Recent advances in understanding oxygen evolution reaction mechanisms over iridium oxide: This paper provides insights into the oxygen evolution reaction (OER) mechanisms on iridium oxide, crucial for improving catalytic processes in industrial applications (Naito et al., 2021).
- Iridium oxide fabrication and application: A review: A comprehensive review that discusses various methods for the fabrication of iridium oxides and their applications, particularly in sensors and catalysts, relevant to both drug discovery and material science (Chen et al., 2020).

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
