Description
Application
It acts as a volatile buffer in protein purification via precipitation mobile phase additive in HPLCMS (replaces non-volatile salts) reagent for organic synthesis of acetamide and in lab diagnostics.
Purpose
Its primary purpose is providing a mild pH 7 buffer (weak acid weak base) that fully volatilizes during analysis avoiding salt interference in mass spectrometry and enabling clean desalting.
General Description
Ammonium acetate is a white hygroscopic crystalline solid formed from ammonium (NH4) and acetate (CH3COO) ions with molecular weight 77.08 gmol density 1.17 gcm at 20C melting point 113114C (decomposes above to acetamide and water) and highly soluble in water (1480 gL cold).
