Ammonium Acetate Purified
Description
Ammonium Acetate Purified is a high-grade, water-soluble, hygroscopic white crystalline solid used across analytical, biochemical, industrial, and agricultural applications.
Chemical and Physical Properties
Chemical formula: CH₃COONH₄ (or NH₄C₂H₃O₂).
Molar mass: 77.08 g/mol.
Appearance: White, odorless, hygroscopic crystalline solid.
Melting point: ~110–114 °C (decomposes).
Readily soluble in water, also soluble in alcohol.
pH (10% solution): around 6.5–7.5.
Major Uses and Applications
Buffer reagent in biochemistry and molecular biology (notably in HPLC and LC-MS for their volatility and low residue).
Used for protein and nucleic acid precipitation and purification protocols.
A mobile phase additive in chromatography (HPLC) and protein mass spectrometry analysis.
Soil testing (for extraction of exchangeable cations and CEC determination).
Used as a biodegradable de-icing agent and in textile and food processing as a pH regulator (food additive INS 264).
Safety and Handling
Hygroscopic: Store in a tightly closed container in a cool, dry place to prevent deliquescence.
Non-flammable, considered environmentally friendly compared to inorganic salts.
Avoid ingestion, inhalation, and contact with skin or eyes; use standard laboratory PPE.
Ammonium Acetate Purified is valued for its high-purity, buffering capacity, and compatibility with sensitive analytical techniques, making it a staple in research and industrial labs.
