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 hydroxide (TMAH) is a potentially lethal chemical that is commonly used in device research as an etchant for silicon and developer for photopatterning1. It is also used for thermochemolysis2, and cleaning DNA microarrays3. It is often used in aqueous solution, but is also occasionally used as a solution in methanol.

Tetramethylammonium hydroxide (TMAOH) is an ion-pairing agent that is usually used in analytical chemistry. It is used in the analysis of marine compounds by thin-layer chromatography-pyrolysis-gas chromatography-mass spectrometry (TLC-pyrolysis-GC/MS) and thermal desorption/capillary GC/inductively coupled plasma mass spectrometry.

2024年4月12日 · TMAH is typically one of several ingredients in etching / stripping mixtures, although it may also be used as a pure chemical. It is often used in solution in water, and less frequently, in methanol. These solutions are assigned the CAS# 75-59-2.

Tetramethylammonium hydroxide (CAS# 75-59-2) is used as a developer and an etchant in micro or nanofabrication. TMAH is a solid in the hydrated form or a colorless liquid when

Tetramethylammonium hydroxide is a strong base used in the o-alkylation of phenolic and carboxylic OH groups. Tetramethylammonium hydroxide is a quaternary ammonium salt generally used as an anisotropic etchant for silicon due to its high silicon etching rate.

Tetramethylammonium hydroxide (TMAH) is a quaternary ammonium salt with the molecular formula (CH3)4NOH. It is widely used in micro- or nanofabrication as an etchant and developer. TMAH is typically one of several ingredients in commercial etching / stripping mixtures, although it may also be used as a pure chemical.
