Descripción general

Ammonium cerium(IV) sulfate dihydrate (tetraammonium cerium(IV) sulphate dihydrate) is commonly employed as starting material for various organic syntheses. It is widely employed as oxidizing agent. Its thermal decomposition and thermal characteristics have been reported.[1]

Aplicación

Ammonium cerium(IV) sulfate may be used for the determination of urinary iodine by ammonium persulfate digestion on microplate (APDM) method[2] and colorimetric method.[3]
Ammonium cerium(IV) sulfate was used in thin-layer chromatography for the detection of anti-depreβant drugs in human blood and urine samples. [4]

An assessment of the potential of proline to scavenge free radicals was made in a couple of in vitro assay systems, namely graft co-polymerization and autooxidation of pyrogallol. Both these assays are essentially dependent upon free radical mechanisms. Graft co-polymerization
