General description
Triethylamine (TEA), also known as N,N-Diethylethanamine, is an aliphatic tertiary amine and a volatile organic compound. It is a colorless liquid with a strong ammonia-like odor and exhibits polar solvent characteristics, although it is less polar than many common laboratory solvents. Triethylamine is used in various industrial processes, including oxidation, reduction, elimination, and dehydrohalogenation reactions.
Application
Triethylamine (TEA) is used
- As a mobile phase modifier to improve the efficiency of separation in micellar liquid chromatography (MLC).
- To prepare the mobile phase for HPLC chromatography
- As the extractant in a hexane solution to extract nickel (Ni) ions from water.

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

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
