Description

Cuprous Iodide is a versatile inorganic compound with the chemical formula CuI, widely recognized for its role as a catalyst and reagent in organic synthesis. Its primary commercial value lies in its ability to facilitate key coupling reactions, such as the Sonogashira and Heck reactions, which are fundamental for constructing complex molecules in pharmaceutical and agrochemical research. This product is essential for manufacturers and R&D laboratories in the fine chemical, electronics, and catalyst industries seeking reliable, high-purity materials for advanced synthesis and material science applications.

Application

• Organic Synthesis Catalyst: A crucial reagent in cross-coupling reactions (e.g., Sonogashira, Heck) for creating carbon-carbon bonds in pharmaceutical intermediates.
• Electronics Manufacturing: Used in the production of semiconductors, photovoltaic cells, and as a component in iodide-based scintillation crystals for radiation detection.
• Animal Feed Additive: Serves as a dietary source of essential iodine and copper in trace amounts for livestock nutrition.
• Cloud Seeding: Employed as a nucleating agent in weather modification programs to induce rainfall.
• Analytical Chemistry: Utilized as a reagent in specific titration methods and for the detection of mercury.
• Photography & Dyes: Historically used in photographic emulsions and as a colorant in certain pigments and dyes.

Quality Control

Our Cuprous Iodide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, heavy metal content, and other critical parameters. Certificates of Analysis (COA) are provided with every shipment, detailing the results of tests such as assay, loss on drying, and impurity profiles. We can supply grades suitable for various industrial applications, including technical and reagent grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain stability and purity. Keep away from strong acids and strong oxidizing agents.
