Description and Uses

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).
