Descrição geral

Triethyl amine (TEA) is an aliphatic tertiary amine.

Aplicação

Triethylamine has been used to bind the n-hydroxysuccinimide (NHS) group with the amino-treated tip surface. It has also been used as a basic catalyst for acylation.

Ações bioquímicas/fisiológicas

Triethylamine (TEA) may play a dual role as a base and a solubilizing agent for promoting the reaction in toluene and TEA.
Triethylamine, a mobile-phase modifier, is used in the reversed-phase high-performance liquid chromatography (RP-HPLC) separation of acidic, basic, and neutral molecules. It improves the resolution of amino acids and amino acids amides by suppressing the tailing and the stability of drugs and other compounds.

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.
