Description

Hydrogen Cyanide CAS NO 74-90-8 is a highly volatile, colorless liquid or gas with a characteristic bitter almond odor. It is a critical chemical intermediate in the synthesis of numerous industrial and agricultural compounds. This product is essential for manufacturers in the chemical, pharmaceutical, and mining sectors requiring a reliable source of high-purity cyanide chemistry.

Application

• Chemical Synthesis: A key precursor for producing adiponitrile, a major intermediate in nylon 6,6 manufacturing.
• Acrylic Polymers: Used in the production of methyl methacrylate (MMA) and subsequently polymethyl methacrylate (PMMA) plastics and resins.
• Agrochemicals: Serves as a building block for various herbicides, insecticides, and fumigants.
• Pharmaceutical Intermediates: Employed in the synthesis of complex molecules, including certain vitamins and pharmaceuticals.
• Metal Plating & Extraction: Utilized in electroplating baths and in the extraction of gold and silver from ores (cyanidation process).
• Chemical Warfare Agent Precursor: Subject to strict international controls and regulations due to its potential misuse.

Quality Control

Our Hydrogen Cyanide is manufactured and handled under stringent safety and quality protocols. Production adheres to relevant industry standards, and each batch is rigorously analyzed to ensure purity and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed, specially designed container under an inert atmosphere (e.g., nitrogen), protected from light and moisture. Due to its highly volatile and toxic nature, storage must be in a dedicated, well-ventilated, cool area (recommended below 20°C/68°F) away from strong acids, bases, oxidizers, and heat sources. Strict compliance with all local, national, and international regulations for hazardous material storage is mandatory.
