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
- Chemiresistive Sensor Development: Diethylamine was used to enhance the sensitivity of a chemiresistive sensor for CO2 gas monitoring, demonstrating its utility in environmental and industrial applications (Rath et al., 2024).
- Supercritical Fluid Chromatography: Aromatic stationary phases were synthesized using diethylamine, evaluated based on the linear solvation energy relationship model, which expanded its application in supercritical fluid chromatography (Ge et al., 2024).
- Nanoparticle Synthesis: Diethylamine facilitated the sol-gel method modifications for synthesizing silver-silica nanoparticles, enhancing their theranostic potential in cancer treatment (Nikolopoulou et al., 2023).
- Pharmaceutical Analysis: Diethylamine was key in developing a novel enantioselective high-performance liquid chromatography-mass spectrometry method, applied to differentiate dextro- and levo-methorphan in post-mortem samples, showcasing its critical role in forensic and clinical toxicology (Jorbenadze et al., 2024).

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
