Potassium tert-pentyloxide, 25% w/w in toluene

Description

CAS: 41233-93-6 | C5H11KO | 126.24 g/mol

Potassium tert-pentyloxide is a strong, hindered base used in combination with lithium diisopropyl amide to generate a superbase for the selective metallation of the aralkyl system at the 6-position of protected estradiols. It is used in organic synthesis, agrochemicals, pharmaceuticals, colorants and aroma chemicals. It acts as a catalyst in polymerization and isomerizations.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
