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
- mild base to neutralize the reaction mixture during the synthesis of 1,2:5,6-Di-O-cyclohexylidene-D-mannitol, and 2,3-Cyclohexylidene-D-glyceraldehyde.
- precipitating agent in the co-precipitation method in the synthesis of gamma alumina (γ-Al2O3) catalyst during the methanol dehydration reaction to produce Dimethyl ether.
- a pore-forming agent and CO2 source to enhance the substrate porosity during the formation of a porous poly(ethersulfone) support layer for designing high-performance thin-film composite forward osmosis (TFC-FO) membranes.
- Contactless conductivity sensor employing moist paper as absorbent for in-situ detection of generated carbon dioxide gas.: This study utilizes sodium bicarbonate in a novel approach for the development of a contactless conductivity sensor. The sensor uses moist paper to absorb CO2 gas generated from sodium bicarbonate, demonstrating its potential for environmental monitoring and analytical applications (Sonsa-Ard et al., 2020).

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
