Pyridinium chlorochromate CAS 26299-14-9 is compared with other commonly used chromium-containing oxidants such as jons reagent, Colljn reagent, etc. It has strong oxidizing ability, good selectivity, and the olefinic bond of the substrate molecule Chemicalbook is not affected during the oxidation process. , and easy to operate. In addition, the acidity of PCC is weaker, so those groups that are not stable to acid can still be preserved during oxidation.
Believe Chemical is a leading China Pyridinium chlorochromate CAS 26299-14-9 manufacturer, supplier and exporter. Adhering to the pursuit of perfect quality of products, so that our Pyridinium chlorochromate CAS 26299-14-9 have been satisfied by many customers. Shandong Believe Chemical Pte. Ltd. is a high-tech enterprise integrating R &D and sales of chemical technology. We are good at the advantages of chemical products in the field.
Our products are exported to Europe, the United States, Japan, South Korea, Southeast Asia and other countries and regions.

Pyridine chlorochromate, commonly abbreviated NBS, is a mild oxidizing agent with orange-yellow crystals. For the limited oxidation of alcohols to aldehydes, the disadvantages of using PCC are the lengthy reaction times and the toxicity of PCC. The reagent itself is weakly acidic, so it is often used in conjunction with a buffer such as sodium acetate.
Oxidizer, selectively oxidizes alcohol. In the Grubbs-catalyzed ring-closure decomposition of D-glucose to synthesize unsaturated lactones for the oxidation of allylmethylene groups.
