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.

Descripción general
Aplicación
- Determination of main fruits in adulterated nectars by ATR-FTIR spectroscopy combined with multivariate calibration and variable selection methods.: This study highlights the application of ATR-FTIR spectroscopy, a technique involving Copper(II) sulfate pentahydrate, in identifying fruit content in adulterated nectars, illustrating its relevance in food chemistry and quality control (de Souza SVC et al., 2018).
- Measurement of electron paramagnetic resonance using terahertz time-domain spectroscopy.: This research demonstrates the use of terahertz time-domain spectroscopy, involving Copper(II) sulfate pentahydrate, to measure electron paramagnetic resonance, contributing to advancements in spectroscopic methodologies (Hangyo M et al., 2011).
- Effects of Curcuma xanthorrhiza Extracts and Their Constituents on Phase II Drug-metabolizing Enzymes Activity.: Though indirectly related, this article explores the role of natural extracts on enzyme activity, providing a context where Copper(II) sulfate pentahydrate could be used as a comparative standard in bioanalytical settings (Ab Halim MR et al., 2016).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 respuesta-
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
