Aplicação

Ammonium citrate dibasic is generally used as a component of matrix solution in matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry analysis. It can also be used as both the carbon and nitrogen source to synthesize fluorescent nitrogen-doped carbon nanoparticles (CNPs).

Oligonucleotides synthesized on a montmorillonite catalyst were analyzed directly. By mixing the catalyst with a matrix (2,4,6-trihydroxyacetophenone or 6-aza-2-thiothymine) and dibasic ammonium citrate, higher molecular weight products were detected compared with "classical" methods such as gel electrophoresis and HPLC with
