- Convenient metering for continuous/batch processes where consistent molarity matters.
Advantages of Potassium tert-Butoxide
- Ready-to-use strong, non-nucleophilic base in a solvent that dissolves many organics — consistent dosing and reproducibility.
- Avoids handling/dust hazards of the solid base – improves operator safety and ease of scale-up.
- Highly effective for eliminations, deprotonations and base-promoted metalations (e.g., generating enolates).
- Concentrated solutions reduce solvent waste and simplify metering in continuous or batch processes.
