Copper(I) Iodide CAS 7681-65-4 Purity >99.0% (Chelometric Titration)

Copper(I) Iodide or Cuprous Iodide (CAS: 7681-65-4) is almost insoluble in water and ethanol, soluble in liquid ammonia, dilute hydrochloric acid, potassium iodide, potassium cyanide or sodium thiosulfate solution, can be decomposed by oncentrated sulfuric acid and concentrated nitric acid. The acidic solution of copper sulfate is added excess potassium iodide or under stirring, a mixed solution of potassium iodide and sodium thiosulfate was added dropwise to a solution of copper sulfate, to obtain precipitation of cuprous iodide. In addition to general purpose use as reagents, etc., but also can be used as power-iodide thermal paper conductive layer material, medical sterilization, mechanical bearing temperature agent, but also used for analysis of trace mercury. Toxicity: Prolonged and repeated contact with the body is harmful, should avoid direct contact with the body. Ingestion is great harm to the body. Copper catalyst/base admixture useful for screening reactions involving the N-arylation of nitrogen-containing heterocycles. Copper(I) Iodide is used as a catalyst for N-arylation of amines and amino acids and in the synthesis of sulfenamides. It is an optimal catalyst for stereospecific and regioselective reaction of silacyclopropanes with carbonyl compounds.A catalyst for N-arylation of amines and amino acids.
