Potassium tert-pentoxide solution
Potassium tert-pentoxide solution (CAS: 41233-93-6), chemical formula CH3CH2C(CH3)2OK, presents as a strong organic base. This solution, typically around 25% in toluene (approx. 1.7 M), is a valuable reagent in organic synthesis. Its powerful basicity makes it effective in deprotonation reactions and as a catalyst in various chemical transformations requiring a robust non-nucleophilic base.
