Ammonium acetate, 97%, Thermo Scientific Chemicals

Description

Ammonium acetate is widely utilized as a catalyst in the Knoevenagel condensation. It is the primary source of ammonia in the Borch reaction in organic synthesis. It is used with distilled water to make a protein precipitating reagent. It acts as a buffer for electrospray ionization (ESI) mass spectrometry of proteins and other molecules and as mobile phases for high performance liquid chromatography (HPLC). Sometimes, it is used as a biodegradable de-icing agent and an acidity regulator in food additives.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
