Description

Potassium Cyanide is a highly reactive inorganic salt with the chemical formula KCN. It is a critical reagent in numerous industrial synthesis and extraction processes, valued for its strong complexing ability with precious metals. This compound is essential for manufacturers and laboratories engaged in gold mining, electroplating, and organic chemical production. We supply high-purity Potassium Cyanide CAS NO 151-50-8 to meet the stringent demands of these specialized global industries.

Application

• Gold and Silver Ore Extraction: The primary industrial use, where it forms soluble complexes to leach precious metals from ores.
• Electroplating: Used in baths for electroplating gold, silver, and other metals onto surfaces for decorative and functional coatings.
• Organic Synthesis: Serves as a source of cyanide ion (CN⁻) in the synthesis of nitriles, carboxylic acids, and various pharmaceuticals.
• Fumigation: Employed in controlled fumigation processes for pest control in shipping and agriculture (subject to strict regulatory controls).
• Chemical Reagent: Used in analytical chemistry and laboratory research for titration and as a reducing agent.
• Metal Cleaning and Hardening: Applied in specific metal treatment and surface hardening processes.

Quality Control

Our Potassium Cyanide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise purity and compositional specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical parameters is provided with every shipment to guarantee traceability and compliance with your operational standards.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, well-ventilated area dedicated for hazardous materials, away from acids, strong oxidizers, and moisture. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under dry, inert conditions when not in use. Follow all local and international regulations for storing highly toxic substances.
