Chemical compound
Not to be confused with Trimethylammonium.
Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me4N]+ and consists of four methyl groups (−CH3, denoted Me) attached to a central nitrogen atom. The cation is isoelectronic with neopentane (Me4C). It is positively-charged and can only be isolated in association with a counter-ion. Common salts include tetramethylammonium chloride and tetramethylammonium hydroxide. Tetramethylammonium salts are used in chemical synthesis and in pharmacological research. It confers no color to its salts.
