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
- Cyclic siloxanes conjugated with fluorescent aromatic compounds as fluoride sensors: This study explores the use of cyclic siloxanes conjugated with aromatic compounds for sensing applications, offering a pathway for academic chemists interested in sensor technology and fluorescence studies (N Prigyai et al., 2020).
- Synthesis, film morphology and performance of novel crosslinked polysiloxane with end-capped epoxy groups on cotton substrates: This article examines the chemical modification of cotton substrates using polysiloxane derivatives, which can be crucial for developing advanced textile coatings (L Hao et al., 2014).
- Stabilizing Li-rich layered oxide cathode interface by using silicon-based electrolyte additive: This research investigates the use of a silicon-based additive derived from 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane to enhance the stability of lithium-rich cathodes, important for chemists working with energy storage technologies (T Huang 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
