Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me 4 N] + and consists of four methyl groups ( −CH 3 , denoted Me) attached to a central nitrogen atom.
Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with molecular formula N(CH 3) 4 + OH −. It is commonly encountered in form of concentrated solutions in water or methanol. TMAH in solid state and its aqueous solutions are all colorless, but may be yellowish if impure.
Tetramethylammonium chloride is a major industrial chemical, being used widely as a chemical reagent [1] and also as a low-residue bactericide in such processes as hydrofracking. [2] In the laboratory, it has fewer synthetic chemical applications than quaternary ammonium salts containing longer N-alkyl substituents, which are used extensively ...
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Tetraethylammonium (TEA) is a quaternary ammonium cation with the chemical formula [Et 4 N] +, consisting of four ethyl groups (−C 2 H 5, denoted Et) attached to a central nitrogen atom.
Trimethylamine is used in the synthesis of choline, tetramethylammonium hydroxide, plant growth regulators, herbicides, strongly basic anion exchange resins, dye leveling agents and a number of basic dyes. [5] [6] Gas sensors to test for fish freshness detect trimethylamine.
Tetramethylammonium fluoride, commonly abbreviated TMAF, is the quaternary ammonium salt with the formula (CH 3) 4 NF. This hygroscopic white solid is a source of ...
