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
Features and Benefits
- 99.999% trace metals basis NaCl in concentrated solar power applications is essential for preventing contamination, ensuring thermal stability, maintaining consistent performance, reducing corrosion risks, and improving energy conversion efficiency.
- 99.999% sodium chloride ensures it is free from trace metals and impurities that could disrupt reactor operations, preventing unwanted chemical reactions that affect the stability and performance of the molten salt.
- 99.999% purity of sodium chloride is critical in molten salt reactors as it enhances chemical stability, minimizes contaminants, improves heat transfer efficiency, reduces risks associated with fission products, ensures consistent performance, and contributes to overall safety.

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
