Description

Cupric Chloride Hydrate is an inorganic salt of copper, widely recognized for its role as a versatile catalyst and reagent in organic synthesis. Its significance lies in providing a controlled source of copper(II) ions, which are essential for numerous oxidation, chlorination, and coupling reactions. This compound is a critical raw material for industries including electronics for printed circuit board (PCB) manufacturing, agriculture as a micronutrient and fungicide, and chemical synthesis for producing pigments and other copper salts.

Application

• Electronics Manufacturing: Essential etchant in the production of printed circuit boards (PCBs).
• Organic Synthesis: Acts as a catalyst or oxidizing agent in various reactions, including the Sandmeyer reaction and Gattermann-Koch formylation.
• Agriculture: Used as a micronutrient fertilizer to correct copper deficiencies in soils and as a fungicide in Bordeaux mixture.
• Pigments & Dyes: Serves as a precursor for the manufacture of copper-based pigments, such as phthalocyanine greens and blues.
• Wood Preservation: Employed in formulations to protect timber from fungal decay and insect damage.
• Analytical Chemistry: Utilized as a reagent in analytical tests and as a source of copper ions in laboratory research.
• Metal Surface Treatment: Used in processes for coloring and patination of copper, brass, and bronze.
• Water Treatment: Applied in specific algicidal and molluscicidal treatments.

Quality Control

Our Cupric Chloride Hydrate is manufactured under a stringent quality management system. 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) documenting these results are provided with every shipment to guarantee traceability and batch-to-batch consistency for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of moisture from the air. Recommended storage temperature is 15-25°C.
