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
- milde Base zur Neutralisierung des Reaktionsgemisches während der Synthese von 1,2:5,6-Di-O-Cyclohexyliden-D-mannitol und 2,3-Cyclohexyliden-D-glyceraldehyd.
- Präzipitationsmittel bei der Co-Präzipitationsmethode bei der Synthese des Gamma-Aluminiumoxid(γ-Al2O3)-Katalysators während der Methanol-Dehydrierungsreaktion zur Bildung von Dimethylether.
- als porenbildender Wirkstoff und CO2-Quelle zur Verbesserung der Substratporosität bei der Bildung einer porösen Polyethersulfon-Trägerschicht zur Entwicklung von Hochleistungs-Dünnschicht-Komposit-Vorwärtsosmose-Membranen (TFC-FO).
- Contactless conductivity sensor employing moist paper as absorbent for in-situ detection of generated carbon dioxide gas.: In dieser Studie wird Natriumbicarbonat in einem neuartigen Ansatz zur Entwicklung eines kontaktlosen Leitfähigkeitssensors verwendet. Der Sensor verwendet feuchtes Papier, um das aus Natriumbicarbonat erzeugte CO2-Gas zu absorbieren, was sein Potenzial für die Umweltüberwachung und analytische Anwendungen belegt (Sonsa-ARD et al., 2020).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 Antwort-
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
