Description

p-Chloranil is used as a dye intermediate, oxidizing agent, vulcanizing agent and dehydrogenation reagent. It is also used to make chloranil electrodes for pH measurements. Further, it serves as a hydrogen acceptor and used for the aromatization reactions such as conversion of cyclohexadienes to the benzene derivatives. It is used to test the secondary amine. In addition to this, it is employed as a precursor to prepare diaziquone, which is used as a cancer chemotherapeutic agent.

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.
