Important Safety Warning
Sodium Nitrite is toxic if swallowed and is a strong oxidizer. It must be handled with extreme care by trained personnel using appropriate personal protective equipment (PPE). Keep away from combustible materials. Not for human consumption.
Frequently Asked Questions
Q: What is the primary use of Sodium Nitrite in the lab?
A: In a laboratory setting, Sodium Nitrite is a crucial reagent for converting amines into diazonium compounds (diazotization), which are versatile intermediates for synthesizing a wide range of organic compounds, especially azo dyes.
Q: How does it work as a corrosion inhibitor?
A: Sodium Nitrite acts as an anodic inhibitor. It passivates the surface of steel by forming a protective, insoluble gamma iron oxide film, which prevents further corrosion. It is particularly effective in closed-loop cooling systems and industrial process water.
Q: Is this the same as the Sodium Nitrite used for curing meat?
A: No. This is a high-purity Analytical Reagent (AR) grade intended for laboratory and industrial use only. Food preservation requires a specific “food grade” product that meets different regulatory standards. Do not use this product for any food-related applications.
