Tetrabutylammonium Hydroxide (TBAH/TBAOH/TBA-OH) is an strong organic base that can be used in a variety of applications from advanced semiconductors to organic chemistry. TBAH is used as an eluent and regenerant for ion chromatography.
SACHEM supplies TBAH in a variety of concentrations and solvents like methanol.
One example is with Sonogashira couplings, which is the reaction between a terminal alkyne and an aryl or vinyl halide in the presence of a base. This powerful synthetic reaction normally requires anhydrous and anaerobic conditions. In this reaction, TBAH provided better yields of 84%. KOH gave only a 3% yield.
Tetrabutylammonium Hydroxide applications:
- Photoresist developer
- Structure directing agent (SDA)
- Flat panel display chemicals
- Advanced Ceramics
- Strong organic base
- Wafer cleaning
- Polymer chemicals
