Tetramethylammonium hydroxide pentahydrate, 98%, Thermo Scientific Chemicals

Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
