Applications

Tetramethylammonium hydroxide pentahydrate is used in analytical chemistry as an ion pairing agent and a polarographic reagent. It finds application in gas chromatography/mass spectrometry (GC/MS), capillary isotachophoresis and capillary zone electrophoresis and liquid chromatography. Furthermore, it is utilized in the preparation of iron oxide nanoparticles which are useful as magnetic resonance imaging contrast agents and tetramethylammonium dithiocarboxylates. It acts as a developer or an etchant in semiconductor and photoelectric industries.

Notes

Air sensitive. Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong acids.
