Overview

Tetramethylammonium hydrogensulfate hydrate is generally used as a phase transfer catalyst. It can also be used as a derivatizing agent for gas chromatography-mass spectrometry (GC-MS)

Applications

Application. Tetramethylammonium hydrogensulfate hydrate is generally used as a phase transfer catalyst. It can also be used as a derivatizing agent for gas chromatography-mass spectrometry (GC-MS) applications.

Dosage and directions

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.

Characteristics and notes

TMAH solution is widely used in the electronics industry as a developer or cleaner. 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.

Safety and SDS

Read the safety data sheet before handling. Wear suitable gloves and eye protection.
