Useful:

• 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

Versatile synthesis of N,S-heterocycles containing the antipyrine moiety

10.1080/104265090969054

The study, titled "Versatile Synthesis of N,S-Heterocycles Containing the Antipyrine Moiety" focuses on synthesizing novel sulfur derivatives with potential biological activity, incorporating the antipyrine moiety. The primary chemicals involved include 4-(chloroacetyl)antipyrine (1) and 4-(cyanoacetyl)antipyrine (14), which serve as key starting materials. Compound 1 reacts with various sulfur nucleophiles, such as O-ethyl xanthic acid potassium salt, 4,5-dihydrothiazole-2-thiol, and pyrimidine-2-thiol, to produce corresponding sul?de derivatives (2–5). Additionally, compound 1 reacts with 2-aminobenzothiazole to form the imidazo[2,1-b]benzothiazole derivative (7). The 2-aminothiazole derivatives (10 and 11) are synthesized via a waste-free, solid-state reaction of compound 1 with thiourea derivatives (8 and 9). These aminothiazole products are then coupled with pyrazolopyridinyl and aromatic diazonium salts to create a series of azo dyes (12 and 13). Furthermore, compound 14 reacts with phenyl isothiocyanate to form a nonisolable adduct (15), which is used as a precursor for synthesizing ketene N,S-acetal (16), dihydrothiazole (17), and thiazolidinone (18) derivatives. The study explores the reactivity of these compounds and their potential applications in medicine and pharmacology, leveraging the known pharmacological properties of antipyrine derivatives.
