Are Copper(I) Iodide, Cuprous Iodide and Copper Iodide the same product?

Copper(I) Iodide and Cuprous Iodide identify CuI, CAS 7681-65-4. The shorter name Copper Iodide can be ambiguous because copper oxidation state matters. Require the formula, CAS number and copper oxidation state on the quotation and batch documents.

Which specifications matter when purchasing Copper(I) Iodide?

Confirm CuI assay and method, copper content, appearance, moisture or loss on drying, insoluble matter, iodide-related impurities and the required trace-metal profile. Catalyst, electronic and general industrial grades can differ substantially, so approve the complete batch analysis for the intended process.

What is Copper(I) Iodide used for?

CuI is evaluated as a copper catalyst or reagent in organic synthesis, as well as in electronic and inorganic-material applications. The required purity, particle properties and trace-metal limits depend strongly on the target process, so the intended use should be stated.

How should Copper(I) Iodide be stored and handled?

Store in tightly closed containers in a cool, dry, ventilated area away from light, moisture, strong oxidizers and incompatible acids. Minimize dust generation, use appropriate PPE and follow the current safety information for handling and spill control.

What are the key physical properties of Copper(I) Iodide?

Copper(I) Iodide is a white to off-white crystalline powder with molar mass about 190.45 g/mol, density around 5.62-5.67 g/cm3, melting point near 605 C and boiling point near 1290 C. It is practically insoluble in water and dilute acids or alcohol, but dissolves in ammonia, thiosulfate and iodide solutions.
