Description and Uses

Ammonium acetate solution can be used to study molecular biology, biological buffers, reagents and DNA and RNA purification. Ammonium acetate solution has been used to study pharmacokinetic analysis of α and β epimers of glycyrrhetinic acid in rat plasma. Ammonium acetate solution has also been used in a study to develop a method for the simultaneous determination of aristolochic acids A and B in some Chinese herbals and traditional Chinese patent medicines.
