Chemical Properties:
Cerium(IV) ion is a potent one-electron oxidant.1 Cerium(IV) Ammonium Nitrate (CAN), is the most widely utilized cerium(IV) oxidizing agent, but cerium(IV) ammonium sulfate (CAS) is a good substitute when complications due to the involvement of nitrate ligands occur, resulting in side products such as nitrate esters.
Handling, Storage, and Precautions:
cerium(IV) ammonium sulfate is a stable reagent and precautions required for handling strong oxidizing agents such as Potassium Permanganate will be sufficient. Cerium is reputed to be of low toxicity.
Applications:
Ammonium Cerium Sulfate is used in preparation of cerium IV oxidimetric solutions, it is an oxidizing agent, used as an oxidizing agent in organic synthesis and as a standard oxidant in quantitative analysis, also used for catalyzer and chemical additives.
Packing: Drum inner with plastic bag. Net weight 25/50 kg.
Storage: Store In Cool, Dry Place In Tightly Closed Containers. Incompatible With Oxidizing Agents.
