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 réponse-
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

In the product information, this product has retained full purity for 5 years when stored in the dark at 2 ~ 8 degrees Celsius. Is it also stable in original white container?
1 réponse-
The information available in the product data sheet refers to the material in the original package, as it is shipped. The information is correct. However, this product is assigned a retest date of approximately 2 years from the date of product release to assure quality. The retest date for each lot is reported on the Certificate of Analysis.

Please provide information about the specific inhibitor and its inhibitory target.
1 réponse-
The specific inhibitor and its inhibitory target are proprietary information. While some products disclose acetanilide as the inhibitor at approximately 200 ppm, and others mention the use of potassium stannate, the exact inhibitor and its target concentration for some products are not publicly stated. Consequently, the specific inhibitor and its inhibitory target remain undisclosed for many hydrogen peroxide products due to the competitive nature of the market.
