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 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

The SDS was received, but there was no Gas Chromatography profile of the components of the mixture. We plan to use this standard in our undergraduate teaching laboratories, so the retention times and order of elution would be helpful
1 answer-
The Safety Data Sheet (SDS) provides chemical data related to safety. For analytical information and certification, refer to the Certificate of Analysis (COA). For this product, the COA can be found in the documentation section of the web page, by entering the lot number in the COA section. The Gas Chromatography (GC) data on the COA show the order of elution of the components and retention time, along with the chromatographic conditions, for the specific lot analyzed.
