Benzyltrimethylammonium hydroxide, 40% w/w in methanol
Description
Benzyltrimethylammonium hydroxide is used as a phase-transfer catalyst. It is also used in aldol condensation reactions and base-catalyzed dehydration reactions. Further, it serves as a strong organic base and used in Horner-Wadsworth-Emmons olefination reactions. In addition, it is an active component in the formulation, which is used in silicon wafer cleaning applications.
