Key Properties
Potassium tert-butoxide hydrate (extra pure) is a strong, bulky, non-nucleophilic base widely used in organic synthesis. It is particularly valued for its ability to deprotonate weak acids and facilitate elimination reactions. This compound is a hydrate form, which enhances its stability and handling properties compared to its anhydrous counterpart. With a high purity of 98%, it is suitable for sensitive applications in research and industrial settings, where precision and reliability are paramount.
Also known as Potassium 2-methyl-2-propanolate.
