설명
Pyridinium dichromate acts as a strong oxidizing agent used in the conversion of primary alcohols and secondary alcohols to aldehydes and ketones respectively. It plays an important role in the oxidation of unsaturated tertiary alcohols, silyl ethers, the carbon-boron bond, and oximes. Further, it is used in the conversion of acetals to esters and didehydroketones to enones in the presence of tert-butyl hydroperoxide.
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.
