DESCRIPTION
General description
Ammonium formate is the ammonium salt of formic acid. It is readily available, is stable and nontoxic in nature. It can be used in conjugation with Palladium on carbon (Pd-C) or Raney-Nickel catalysts.
Application
Ammonium formate has been used as buffer solution during LC-MS/MS analysis for screening of drugs and exogenous compounds. It may be used as a catalytic hydrogen transfer agent in reduction of aliphatic and aromatic nitro compounds. Ammonium formate has been used in the separation of non-steroidal anti-inflammatory drugs and of oligosaccharide mixtures using capillary electrochromatography. It is also used in the analysis of phosphatidylserines, triacylglycerols and triacylglycerol oxidation products, and oligogalacturonic acids using HPLC and HPLC-MS methods.
