General description

Ammonium iron(III)citrate can be used as a reagent and iron precursor in several organic reactions and Fe3O4-based nanomaterial preparation. It can be prepared by treating Fe(OH)3 with citric acid and NH4OH in various ratios.

Application

Ammonium iron(III) citrate can be used as a reagent to prepare amphiphilic siderophore iron acinetoferrin complex from acinetoferrin in the presence of HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) buffer. It can also be used as an iron precursor to prepare Fe3O4-carbon dots magnetic-fluorescent hybrid nanoparticles.
