Application

Ammonium iron(III) sulfate dodecahydrate can be used as:
  • A catalyst to synthesize 1,4-dihydropyridines via one-pot three-component condensation reaction of dimedone, aldehydes, and 3-aminocrotonate in ethanol.
  • An additive in the reduction of aromatic nitro compounds to the corresponding amino compounds in the presence of alumina-supported hydrazine hydrate as a catalyst.

The interaction of microsomes with iron and NADPH to generate active oxygen radicals was determined by assaying for low level chemiluminescence. The ability of several ferric complexes to catalyze light emission was compared to their effect on microsomal lipid peroxidation

Neurobiology of aging, 25(1), 125-129 (2003-12-17)
In order to investigate whether amyloid beta-peptide-induced oxidative damage in the brain could be related to aging, we studied the release of 8-iso-prostaglandin (PG)F2alpha, a stable marker of cellular oxidative stress, in brain synaptosomes from Wistar rats of different ages

Journal of pharmaceutical and biomedical analysis, 14(8-10), 951-958 (1996-06-01)
The method is based upon the reaction between fluoride ions and the coloured complex of Fe(III) with methyl salicylate to form the stable, colourless hexaflouride complex of iron. The conditions of the method (pH, time and combination ratio) were studied

Efficiency was examined of microencapsulating L-ascorbic acid by polyglycerol monostearate (PGMS), and changes in the chemical and sensorial aspects of L-ascorbic acid and/or iron-fortified milk during storage were evaluated. The selected core materials were ferric ammonium sulfate and L-ascorbic acid.

The NADH-dependent microsomal electron transfer system consists of NADH-cytochrome b5 reductase and cytochrome b5, which donates reducing equivalents to fatty acyl desaturase, cytochrome P450, and other reactions. A study was carried out to investigate the interaction of NADH with several
