1-Chloro-2,4-dinitrobenzene is used as a reagent for the detection and determination of pyridine compounds. It has been used as alkylating agent to evaluate the depletion of intracellular erythrocyte glutathione (GSH). It is an irreversible inhibitor of human thioredoxin reductase.
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.
