General description

Triethylammonium acetate, also known as TEAA, is a volatile buffer widely utilized as a buffer in various biochemical and biological applications, particularly in peptide and proteomics research. It is a common choice for ion-pairing reagent in the chromatographic separation of oligonucleotides and plays a key role in buffer solutions for oligonucleotide synthesis and purification.

Application

Triethylammonium acetate has been used:
  • as a buffer in proteomics studies[1]
  • as a component of the mobile phase to separate nucleotide sugars[2]
  • as a buffer for the separation of glycopeptides in proteomics research

Features and Benefits

  • Suitable for Biological and Biochemical Research
  • Ready available solution reduce the need for preparation time

Questions

1–3 of 3 Questions  

  1. 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/418/501/product-dating-information-06-25-mk.pdf

  2. 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

  3. Hi, I want to purchase triethylammonium acetate solid, but it's not available. I wonder if this TEAA buffer made of pure TEAA, or is there anything else added to adjust the pH? Please let me know about other chemical content in this product. Thank you.

    1 answer

    1. This product is a 1M solution in water. Triethylammonium acetate is a mixture of triethylamine and acetic acid. The purity of the specific starting materials is not reported. However, the molarity is confirmed and reported in the lot specific Certificate of Analysis. Please see the link below to review a sample or lot specific Certificate:
