Ammonium acetate is a white crystalline inorganic salt commonly used as a buffer agent in biochemical and chemical applications.
🏭⚗️ Production
It is typically prepared by neutralizing acetic acid with ammonia gas or by reacting ammonium carbonate with acetic acid, followed by crystallization and drying.
🔬 Properties
The chemical formula is NH₄CH₃COO with a molar mass of approximately 77.08 g/mol. It appears as white crystals that are highly soluble in water and form a mildly acidic to neutral solution. It decomposes upon heating to produce ammonia and acetic acid vapors.
🧪 Applications
Ammonium acetate is widely used as a buffer in electrophoresis and chromatography, in pharmaceutical formulations, and as a reagent in organic synthesis. It also serves as a food additive and a catalyst in some chemical reactions.
⚠️ Safety
This compound is generally safe but may cause mild irritation to skin and eyes. Inhalation of dust should be avoided. Use gloves and eye protection when handling and store in a cool, dry place away from strong oxidizers.
