The pK a of protonated triethylamine is 10.75, [4] and it can be used to prepare buffer solutions at that pH. The hydrochloride salt, triethylamine hydrochloride (triethylammonium chloride), is a colorless, odorless, and hygroscopic powder, which decomposes when heated to 261 °C. Triethylamine is soluble in water to the extent of 112.4 g/L at ...
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.
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
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
Tris(2-aminoethyl)amine is the organic compound with the formula N(CH 2 CH 2 NH 2) 3.This colourless liquid is soluble in water and is highly basic, consisting of a tertiary amine center and three pendant primary amine groups.
CH 3 C 6 H 4 SO 2 Cl + ROH → CH 3 C 6 H 4 SO 2 OR + HCl. Tosylates can be cleaved with lithium aluminium hydride: 4 CH 3 C 6 H 4 SO 2 OR + LiAlH 4 → LiAl(O 3 SC 6 H 4 CH 3) 4 + 4 RH. Thus, tosylation followed by reduction allows for removal of a hydroxyl group. Likewise, TsCl is used to prepare sulfonamides from amines: [3] CH 3 C 6 H 4 SO ...
In this reaction, ethylamine is coproduced together with diethylamine and triethylamine. In aggregate, approximately 80M kilograms/year of these three amines are produced industrially. [4] It is also produced by reductive amination of acetaldehyde. CH 3 CHO + NH 3 + H 2 → CH 3 CH 2 NH 2 + H 2 O
Tris is also used as a primary standard to standardize acid solutions for chemical analysis. Tris is used to increase permeability of cell membranes. [ 13 ] It is a component of the Moderna COVID-19 vaccine [ 14 ] and the Pfizer-BioNTech COVID-19 vaccine for use in children 5 through 11 years of age.
