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.

Application
- Electrospraying of Bio-Based Chitosan Microcapsules Using Novel Mixed Cross-Linker: Experimental and Response Surface Methodology Optimization.: Diese Studie wurde in Materials veröffentlicht und untersucht den Einsatz von dibasischem Natriumphosphat als Vernetzungsmittel bei Elektrospray-Verfahren mit Chitosan-Mikrokapseln. Die Studie unterstreicht die Bedeutung der chemischen Substanz bei der Prozessoptimierung der Mikroverkapselung für potenzielle biomedizinische Anwendungen (Uko et al., 2022).
- Compound treatment of thiolated citrus high-methoxyl pectin and sodium phosphate dibasic anhydrous improved gluten network structure.: Dieser Artikel aus Food Chemistry zeigt, wie dibasisches wasserfreies Natriumphosphat die Netzstruktur von Gluten verbessert, wenn es mit thioliertem Citruspektin mit hohem Methoxylgehalt kombiniert wird, was Anwendungen in der Lebensmittelwissenschaft und Ernährung nahelegt (Chen et al., 2023).

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
