Cuprous Iodide

Product Overview

Cuprous Iodide, chemically known as Copper(I) Iodide, represents a critical inorganic compound widely utilized across various industrial and scientific sectors. With the molecular formula CuI and a molecular weight of 190.45, this substance is essential for professionals requiring reliable copper sources for complex chemical transformations. Our manufacturing process ensures consistent quality, making it a preferred choice for laboratories and large-scale industrial facilities alike. The compound typically presents as a white crystal or offwhite powder, though users should note its tendency to turn brownish yellow when exposed to light, indicating the need for proper storage conditions to maintain stability and efficacy over time.

Chemical Properties

Understanding the physicochemical profile of Cuprous Iodide is vital for safe and effective application. The material exhibits a relative density of 5.63, with a melting point of 605℃ and a boiling point of 1290℃, reflecting its thermal stability under standard processing conditions. Solubility characteristics are distinct; it is insoluble in water and ethanol but demonstrates solubility in concentrated sulfuric acid, hydrochloric acid, ammonia water, and potassium iodide solutions. This specific solubility profile distinguishes it from other copper salts and enables its use in specialized reaction environments where aqueous stability is not required. The high purity levels available ensure minimal interference in sensitive catalytic cycles.

Industrial Applications

The versatility of Cuprous Iodide extends across several high-value industries, primarily driven by its catalytic properties and role as a building block in synthesis. Key application areas include:

• Organic Synthesis Catalyst: Frequently employed in coupling reactions such as the Sonogashira coupling, facilitating the formation of carbon-carbon bonds essential for complex molecule construction.
• Pharmaceutical Intermediate: Serves as a crucial reagent in the manufacture of active pharmaceutical ingredients, where strict impurity controls are mandatory.
• Polymer Industry Auxiliaries: Used in the production of auxiliaries for chinlon filature, supporting the textile and synthetic fiber manufacturing sectors.
• Research and Development: Provides a reliable standard for academic and industrial research focused on copper chemistry and coordination complexes.
