설명

일반 설명

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

애플리케이션

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).
