Applicazioni

Tetramethylammonium hydroxide is used to produce tetramethyl-ammonium azide. It is used as an anisotropic etchant of silicon, as a basic solvent in the development of acidic photoresist in photolithography process, as a surfactant in the synthesis of ferrofluid and as a polarographic reagent. It finds application in the production of organic silicon, where it is used for computer silicon wafer surface brighteners and as a cleaning agent. It is also involved in the purification of some metallic elements.

Note

Air sensitive. Incompatible with strong oxidizing agents, strong acids, aluminum, alkali metals, strong oxidizing agents, acids, acid chlorides, acid anhydrides and halogens.
