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

What sealing procedure was used for the ampule containing 469858-5G? There were issues when attempting to reseal the ampule using parafilm. Therefore, a resealing procedure is needed to ensure that the contents can be used over time without crystallizing.
1 answer-
The ampules are intended for one-time use only. For any remaining material, it is advised to transfer it to a bottle with a screw cap in a glove bag under inert atmosphere instead of trying to re-seal the glass ampule. It's important to note that this material is highly sensitive to air and water, so it cannot be guaranteed that the material will not degrade once the ampule has been opened and the contents transferred to a new bottle.
