Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. Like triethanolamine and tetraethylammonium , it is often abbreviated TEA. [ 8 ] [ 9 ] It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia .
Triethanolamine is used primarily in making surfactants, such as for emulsifier.It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in wate
teaa, triethylamine/acetate buffer. Identifiers CAS Number. 5204-74-0 ...
DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2.The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation.
Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a trimethylated derivative of ammonia.TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7]
CAS Number. 75-09-2 ... Hydroxybenzotriazole and related reagents used in peptide coupling react with DCM in the presence of triethylamine, forming acetals. [25]
The selection of the base is often crucial to the efficiency of tosylation. Typical bases include pyridine and triethylamine. Unusual bases are also used; for example, catalytic amounts of trimethylammonium chloride in the presence of triethylamine is highly effective by virtue of the trimethylamine. [2]
