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
- Research on the Synthesis of Zinc-Ammonium Phosphate Using Galvanic Waste Sludge as a Source of Zinc: This study explores a novel approach using hydrochloric acid solution in the synthesis process aimed at valorizing waste materials. The article demonstrates a chemical strategy that enhances resource recovery, significantly contributing to waste minimization in industrial practices (Morgovan et al., 2024).
- Contactless conductivity sensor employing moist paper as absorbent for in-situ detection of generated carbon dioxide gas: The study integrates hydrochloric acid solutions in the development of a novel, cost-effective contactless conductivity sensor. This sensor uses a simple paper-based system for the in-situ monitoring of gases, providing a significant tool in environmental monitoring and analysis (Nacapricha 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
