Useful:

• Chemical Classes: Metals -> Organic Acids, Metal Salts
• Canonical SMILES: CCOC(=S)[S-].[K+]
• Uses: As reagent in analytical chemistry. 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. Potassium ethyl xanthogenate (ethyl potassium xanthogenate) has been used:in synthesis of unsymmetrical sulfides via cross-coupling reaction, using recyclable CuO nanoparticles under ligand-free conditionsas surfactant to investigate the adsorption of colloidal dye Disperse Blue 3 onto pretreated polyester fabricin determination of microgram amounts of cadmium in water samples by substoichiometric radiochemical method
