General description

Triethyl phosphate is an alkyl phosphate. It participates in the thermal transformation of sodium acetate-2-C14 to n-butyl acetate-2-C14.[1]

Application

  • Sensor Technology for Chemical Detection: Triethyl phosphate is utilized in the development of trisaryl phosphoric triamide-based resins for a quartz crystal microbalance sensor, enhancing the detection capabilities for sulfur mustard simulants, which is critical in chemical safety and environmental monitoring (Heo et al., 2024).
  • Flame-Retardant Bio-based Composites: Research highlights the use of triethyl phosphate in creating flame-retardant, energy-storage, and transparent bio-based composites, leveraging natural cellulose templates to enhance both safety and environmental sustainability (Li et al., 2024).
  • Environmental Biodegradation Studies: Triethyl phosphate is instrumental in a novel method for rapidly monitoring organophosphate flame retardants (OPFRs) by liquid-liquid extraction and gas chromatography-mass spectrometry, a significant advancement in environmental science for assessing biodegradation (Losantos et al., 2024).

Questions

1–2 of 2 Questions  

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

    1 answer

    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
