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
- Dithizone modified silver electrode for the determination of metal ions in aqueous solution: This study discusses a dithizone-modified electrode used for the electrochemical determination of various metal ions, highlighting its applications in environmental monitoring and industrial process control (Othman et al., 2016). Source.
- Eco-friendly immobilization of dithizone on coal bottom ash for the adsorption of lead (II) ion from water: This study explores the use of dithizone-immobilized coal ash for the efficient removal of lead from water, demonstrating a cost-effective method for treating contaminated water (Huda et al., 2021). Source.
- Colorimetric Sensing of Pb2+ Ion by Using Ag Nanoparticles in the Presence of Dithizone: The article details the development of a colorimetric sensor for lead ions, which uses silver nanoparticles and dithizone, providing a rapid and sensitive method to detect heavy metal contamination in environments (Roto et al., 2019). Source.
- Dithizone-etched CdTe nanoparticles-based fluorescence sensor for the off–on detection of cadmium ion in aqueous media: This research presents a fluorescent sensor based on dithizone-etched CdTe nanoparticles for detecting cadmium ions, offering applications in environmental monitoring and safety assessments (Li et al., 2017).

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
