Description

Sodium CAS NO 7440-23-5 is a soft, silvery-white, highly reactive alkali metal. It is a fundamental industrial chemical valued for its powerful reducing properties and its role as a precursor in numerous synthesis processes. This essential element is critical for manufacturers in the chemical, pharmaceutical, and metallurgical industries seeking a reliable source for high-purity reactive metals.

Application

• Chemical Synthesis: As a strong reducing agent in the production of organic compounds, dyes, and pharmaceuticals.
• Metallurgy: Used in the refining of certain metals (e.g., titanium, zirconium) and as a desulfurizing and deoxidizing agent in alloys.
• Sodium Vapor Lamps: A key component in high-intensity discharge (HID) lighting for streetlights and industrial lighting.
• Heat Transfer Fluid: Utilized in liquid form as a coolant in specialized nuclear reactors (sodium-cooled fast reactors).
• Reagent Production: Essential for manufacturing sodium-based reagents like sodium hydride (NaH) and sodium alkoxides.
• Polymer Industry: Acts as a catalyst in the production of synthetic rubber (e.g., styrene-butadiene rubber).

Quality Control

Our sodium metal is produced and handled under stringent conditions to ensure high purity and consistent performance. We offer various grades, including industrial and high-purity, with quality verified against standard analytical methods. A Certificate of Analysis (COA) detailing purity and impurity profiles is provided with every shipment to guarantee compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive nature, sodium must be stored under an inert atmosphere (e.g., argon or mineral oil) to prevent oxidation and reaction with moisture. Store in a cool, dry, well-ventilated area away from water, acids, and oxidizing agents. Keep container tightly sealed when not in use.
