TETRAMETHYLAMMONIUM HYDROXIDE 25 WT. % SOLUTION IN WATER (C005B-077219)

General description

Tetramethylammonium hydroxide solution is commonly used as a strong base and nucleophilic source in organic synthesis reactions.

Application

Tetramethylammonium hydroxide is a quaternary ammonium salt generally used as an anisotropic etchant for silicon due to its high silicon etching rate.

Tetramethylammonium hydroxide solution (25 wt.% solution in water) may be used as a base for pH adjustment to obtain hexagonal mesoporous aluminophosphate (TAP).
