معرف نسلر برای نمک های آمونیوم

Nessler’s Reagent for Ammonium Salts is a standardized aqueous solution used for the qualitative and quantitative detection of ammonium ions (NH₄⁺) in laboratory and pharmaceutical applications.

🏭⚗️ Production
Nessler’s Reagent is prepared by dissolving high-purity mercuric iodide and potassium iodide in an alkaline medium, typically potassium hydroxide solution. The reagent is carefully standardized to ensure accurate detection of ammonium ions. It is stored in tightly sealed, light-resistant containers to maintain stability and prevent decomposition.

🔬 Properties
The reagent is a clear to slightly yellowish liquid that is highly soluble in water. It reacts specifically with ammonium ions to form a colored complex, allowing sensitive detection. The solution should be protected from light, heat, and contamination to preserve its effectiveness.

🧪 Applications
In laboratory settings, Nessler’s Reagent is used for the qualitative and quantitative determination of ammonium salts in water, chemical preparations, and pharmaceutical formulations. In pharmaceutical applications, it is employed to monitor residual ammonium levels during synthesis or formulation processes to ensure product safety and compliance with quality standards.

⚠️ Safety
Nessler’s Reagent contains toxic and corrosive mercury compounds and must be handled with extreme care. Contact with skin or eyes should be rinsed immediately with plenty of water, and gloves, goggles, and lab coats must be worn during handling. The reagent should be stored in tightly sealed containers in a cool, dark place, away from incompatible substances. Disposal must follow strict laboratory safety protocols and local environmental regulations.
