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
- Enhanced Battery Performance: Trimethyl phosphate is utilized to manipulate the ionic conductivity and interfacial compatibility in polymer-in-dual-salt electrolytes, significantly extending the operable temperature range of quasi-solid metal batteries (Lin et al., 2024).
- Thermochemical Properties Analysis: Research on trimethyl phosphate′s thermochemistry properties and rate kinetics, particularly H-Atom Abstraction reactions, provides valuable insights into its stability and reactivity, which are crucial for various chemical synthesis applications (Bruce and Li, 2023).
- Organophosphorus Flame Retardants Detection: Trimethyl phosphate is explored for its role in the screening of organophosphorus flame retardant residues in food samples, specifically rice, utilizing advanced chromatographic techniques to ensure food safety and compliance with environmental regulations (Li et al., 2023).
- Interfacial Reaction Regulation in Batteries: The study on regulating interfacial reactions through electrolyte chemistry, involving trimethyl phosphate, highlights its potential to create gradient interphases for low-temperature zinc metal batteries, contributing to enhanced battery safety and efficiency (Wang et al., 2023).

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
