Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with the molecular formula N(CH3)4+ OH−. It is commonly encountered as concentrated solutions in water or methanol. The solid and solutions are colorless, or yellowish if impure. Although TMAH has virtually no odor when pure, samples often have a strongly fishy smell from the trimethylamine which is a common impurity. TMAH has numerous and diverse industrial and research applications.

Tetramethylammonium hydroxide Uses

One of the industrial uses of TMAH is for the anisotropic etching of silicon. It is used as a basic solvent in the development of acidic photoresist in the photolithography process and is highly effective in stripping photoresist. TMAH has some phase transfer catalyst properties and is used as a surfactant in the synthesis of ferrofluid, to inhibit nanoparticle aggregation.

TMAH is the most common reagent currently used in thermochemolysis, an analytical technique involving both pyrolysis and chemical derivatization of the analyte.
