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
- Interactions between irrigants commonly used in endodontic practice: a chemical analysis.: This study explores the chemical interactions between various endodontic irrigants, including phosphoric acid, when used in dental treatments. The findings highlight the potential effects of these interactions on the effectiveness of the treatments (Gomes BP et al., 2013).
- Quantifying phosphoric acid in high-temperature polymer electrolyte fuel cell components by X-ray tomographic microscopy.: This research presents a method for quantifying phosphoric acid concentrations in fuel cell components using advanced X-ray imaging techniques, providing insights into the material characteristics and performance in high-temperature operational environments (Schmidt TJ et al., 2014).
- Activated carbon fibers with a high heteroatom content by chemical activation of PBO with phosphoric acid.: The study discusses the production of activated carbon fibers using phosphoric acid, emphasizing the incorporation of heteroatoms that enhance the material′s adsorptive properties, relevant in various analytical applications in chemistry (Tascon JM et al., 2012).
- Activated carbon fibers with a high content of surface functional groups by phosphoric acid activation of PPTA.: This article investigates the activation of poly(p-phenylene terephthalamide) with phosphoric acid to produce carbon fibers enriched with functional groups, enhancing their utility in chemical separations and catalysis (Tascon JM et al., 2011).
- Phosphoric acid purification sludge: Potential in heavy metals and rare earth elements.: This research evaluates the potential of phosphoric acid sludge as a source of heavy metals and rare earth elements, offering a perspective on waste valorization and resource recovery in environmental chemistry (Moutte J et al., 2019).

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
