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

How long it stable in media stored in 4℃?
1 answer-
TS Final Answer: Classical media products containing 2 mM L-glutamine are stored at 2-8°C. These prepared solutions are assigned a shelf life of approximately 18 months. At similar or higher concentrations, in a pH range of 7.2 - 7,6, when protected from light, a similar shelf life is expected. Please see the image below to review the published stability study of L-Glutamine.

Is the molecular weight of L-Glutamine 146.14 or 146.15? The label information changed.
1 answer-
Based on a molecular formula of C5H10N2O3, the molecular weight to seven significant figures is 146.1456. Over the years, this value may have been reported in Sigma-Aldrich documentation or on labels as either 146.15 (by rounding up) or 146.14 (by truncation). The material itself has not changed.
