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
- Facile synthesis of light harvesting semiconductor bismuth oxychloride nano photo-catalysts for efficient removal of hazardous organic pollutants: Diese Studie zeigt die Verwendung von Hydroxylammoniumchlorid bei der Synthese von Bismutoxychlorid-Nano-Photokatalysatoren. Diese Katalysatoren werden für den Abbau gefährlicher organischer Verbindungen eingesetzt, was eine wichtige Anwendung in der Umweltsanierung und der analytischen Chemie darstellt (Seddigi ZS et al., 2017).
- On-column derivatization using redox activity of porous graphitic carbon stationary phase: an approach to enhancement of separation selectivity of liquid chromatography: Dieser Artikel befasst sich mit der Verwendung von Hydroxylammoniumchlorid bei der Säulenderivatisierung bei Flüssigkeitschromatographieprozessen. Der Fokus liegt auf der Verbesserung der Trennselektivität, die eine zentrale Rolle bei der Verfeinerung von Analysemethoden für komplexe Gemische spielt (Shibukawa M et al., 2003).

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
