Description

Cobalt Chloride CAS NO 1332-82-7 is an inorganic salt of cobalt, widely recognized for its role as a versatile precursor and catalyst in numerous industrial processes. Its hygroscopic nature makes it a critical reagent in humidity indicator applications and a key component in the synthesis of other cobalt compounds. This product is essential for manufacturers and R&D facilities in the chemical, catalyst, and specialty materials sectors.

Application

• Catalyst Production: A key precursor in the manufacture of catalysts for petroleum refining, hydrodesulfurization, and Fischer-Tropsch synthesis.
• Humidity Indicators: Used in desiccants and humidity-indicating cards due to its distinct color change from blue (anhydrous) to pink (hydrated).
• Electroplating & Surface Treatment: Serves as a source of cobalt ions in electroplating baths to deposit cobalt or cobalt alloy coatings.
• Pigment & Dye Intermediate: Employed in the production of cobalt blue pigments and as a mordant in dyeing processes.
• Chemical Synthesis: Acts as a starting material or reagent in organic synthesis and the preparation of other cobalt salts.
• Nutritional Supplements & Animal Feed: Used as a source of the essential trace element cobalt in specific, highly regulated formulations.
• Laboratory Reagent: Utilized in analytical chemistry and research as a standard or testing agent.

Quality Control

Our Cobalt Chloride is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal humidity exposure. Recommended storage temperature is between 15°C and 25°C. Ensure the storage area is well-ventilated and separate from incompatible materials.
