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
- Visible-light excitable Eu(3+)-induced hyaluronic acid-chitosan aggregates with heterocyclic ligands for sensitive and fast recognition of hazardous ions: Utilizes 1,10-phenanthroline monohydrate in environmental sensing applications to detect hazardous ions efficiently (Aleem AR, Ding W, Liu J, Li T, Guo Y, Wang Q, Wang Y, Rehman FUL, Kipper MJ, Belfiore LA, Tang J, 2021).
- Structural diversity of copper(I) complexes formed by pyrrole- and dipyrrolylmethane-based diphosphine ligands with cu-X···HN hydrogen bonds: Researches the coordination chemistry of 1,10-phenanthroline monohydrate, highlighting its role in forming novel copper(I) complexes (Kumar S, Mani G, Dutta D, Mishra S, 2014).
- Direct electron transfer from glucose oxidase immobilized on polyphenanthroline-modified glassy carbon electrode: Demonstrates the use of 1,10-phenanthroline monohydrate in biosensor applications for direct electron transfer mechanisms (Oztekin Y, Ramanaviciene A, Yazicigil Z, Solak AO, Ramanavicius A, 2011).

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
