Potassium ethyl xanthate, 97+%, Thermo Scientific Chemicals

Description

Potassium ethyl xanthate is used as a reagent for extraction of metal ions into organic solvents and in the preparation of 2-mercapto benzimidazoles and 2-mercapto benzoxazoles by reacting with o-phenylenediamines and o-amino phenols respectively. It acts as a precursor in the production of unsymmetrical sulfides through cross-coupling reaction and as a floatation agent in the mining industry. It is involved in the determination of cadmium in water samples by substoichiometric radiochemical method and the adsorption of colloidal dye disperse Blue 3 onto pretreated polyester fabric.

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.
