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 ...
The hydrochloride salt of TETA, referred to as trientine hydrochloride, is a chelating agent that is used to bind and remove copper in the body to treat Wilson's disease, particularly in those who are intolerant to penicillamine. [11] Some recommend trientine as first-line treatment, but experience with penicillamine is more extensive. [16]
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.
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
Trimethylamine is a full agonist of human TAAR5, [13] [14] [15] a trace amine-associated receptor that is expressed in the olfactory epithelium and functions as an olfactory receptor for tertiary amines. [15] [16] One or more additional odorant receptors appear to be involved in trimethylamine olfaction in humans as well. [16]
Sample of a hydrochloride salt, triethylammonium chloride. In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French.
The by-products are dimethyl sulfide ((CH 3) 2 S), carbon monoxide (CO), carbon dioxide (CO 2) and—when triethylamine is used as base—triethylammonium chloride (Et 3 NHCl). Of the volatile by-products, dimethyl sulfide has a strong, pervasive odour and carbon monoxide is acutely toxic, so the reaction and the work-up needs to be performed ...
Trimethylamine oxide is used in protein folding experiments to counteract the unfolding effects of urea. [15] In the organometallic chemistry reaction of nucleophilic abstraction, Me 3 NO is employed as a decarbonylation agent according to the following stoichiometry: M(CO) n + Me 3 NO + L → M(CO) n−1 L + Me 3 N + CO 2
