Tetramethylammonium chloride is one of the simplest quaternary ammonium salts, with four methyl groups tetrahedrally attached to the central N. The chemical formula (CH 3) 4 N + Cl − is often abbreviated further as Me 4 N + Cl −. It is a hygroscopic colourless solid that is soluble in water and polar organic solvents.
In the early pharmacological literature, however, there are references to the use of "tetramethylammonium hydroxide" or "tetramethylammonium hydrate", which were meant to facilitate comparison between weight-based dosages of different TMA salts, [18] but did not involve the actual use of tetramethylammonium hydroxide, whose strong basicity ...
The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...

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.
The perchlorate is used as an intermediate in organic synthesis, in chromatography and as a supporting electrolyte in electrochemistry. [3] Along with trimethylammonium perchlorate, it was investigated as a component in composite propellants during the Cold War, but without much success.
