Product Description
Chemical Properties
Molecular Formula: CuI
Molecular Weight: 190.45 g/mol
CAS Number: 7681-65-4
Appearance: Typically a white solid, but can appear tan or reddish-brown due to impurities.
Melting Point: 606 C
Boiling Point: 1,290 C (decomposes before boiling)
Density: Approximately 5.62 g/cm
Solubility: Poorly soluble in water (0.00042 g/L at 25 C) but soluble in concentrated solutions of potassium iodide or sodium thiosulfate.
Structure
Copper iodide exists in several crystalline forms depending on the temperature:
Zinc Blende Structure: Below 390 C (-CuI)
Wurtzite Structure: Between 390 and 440 C (-CuI)
Rock Salt Structure: Above 440 C (-CuI)
The ions in these structures are tetrahedrally coordinated, with a Cu-I bond length of approximately 2.338 in the zinc blende and wurtzite forms.
Applications
Copper iodide is utilized in various fields:
Organic Synthesis: Acts as a catalyst in cross-coupling reactions, such as the synthesis of aryl amines and other organic compounds.
Cloud Seeding: Used to induce precipitation by dispersing it into clouds.
Heat Stabilization: Employed in nylon production to enhance heat resistance.
Biochemical Applications: Functions as a carrier of iodine in biochemical pathways due to its limited solubility in water.
Safety Information
Copper iodide poses certain hazards:
Toxicity: While it has relatively low toxicity, it can cause irritation to the skin and eyes.
Handling Precautions: Use appropriate personal protective equipment (PPE), including gloves and safety goggles. Ensure good ventilation when handling the compound.
