Description

Cyanide CAS NO 57-12-5 refers to a class of chemical compounds containing the cyano group (-C≡N), with sodium cyanide and potassium cyanide being the most commercially significant salts. This compound is a critical industrial chemical primarily valued for its strong affinity for metals, making it indispensable in metal extraction and processing. It is a key raw material for manufacturers in the mining, electroplating, and chemical synthesis industries who require a reliable and high-purity source for their processes.

Application

• Gold and Silver Mining: The primary global application, used in the cyanidation process to selectively leach precious metals from ore.
• Electroplating: Serves as a complexing agent in baths for electroplating metals like gold, silver, copper, and zinc, providing smooth and adherent coatings.
• Chemical Synthesis: Acts as a fundamental building block in organic chemistry for the production of nitriles, carboxylic acids, and various pharmaceuticals and agrochemicals.
• Metal Cleaning and Hardening: Used in case hardening of steel (cyaniding) and in specialized metal surface treatment formulations.
• Fumigant: Historically used in pest control, though this application is now highly restricted and regulated.
• Laboratory Reagent: Employed in analytical chemistry and research as a standard reagent for titration and synthesis.

Quality Control

Our cyanide products are manufactured under strict quality management systems. Each batch undergoes comprehensive 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 as standard, ensuring traceability and compliance for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area dedicated for toxic substances. Keep away from acids, strong oxidizers, and moisture. Storage temperature should be maintained at a stable room temperature (15-25°C).
