Ammonium Cerium(IV) Nitrate (CAN; Ceric Ammonium Nitrate) (CAS: 16774-21-3) is used as a volumetric oxidizing reagent in many oxidation-reduction titrations. Cerium(IV) ion is a strong oxidant similar to permanganate ion. It is the most widely-used primary standard among all Ce(IV) compounds. Other applications of this compound are in organic oxidation reactions; and as a catalyst in polymerization of olefins. A strongly oxidizing cerium preparation.
Ammonium Cerium(IV) Nitrate is a versatile reagent, it has great potential in organic synthesis. It not only has good reaction selectivity, but also has high yield. With the development and utilization of the reagent, it will play a more important role in organic synthesis.
Ammonium Cerium(IV) Nitrate is a strong oxidant, which is more oxidative under acidic conditions, second only to F2, xeO3, Ag2 +, O3, hn3. In aqueous solutions and other protic solvents, CAN is a single electron oxidant, and the change in color (from orange to light yellow) CAN consumption CAN be judged. Due to the limitation of solubility in organic solvents, the reactions in which CAN participates are mostly carried out in mixed solvents such as water/acetonitrile. In the presence of other oxidants such as sodium bromate, tert-butyl hydroperoxide and oxygen, etc., the recycling of Ce4 + can be achieved to achieve a catalytic reaction. In addition, CAN is also an effective nitrification reagent.
Ammonium Cerium(IV) Nitrate is a very strong oxidizing agent. Ammonium cerium(IV) nitrate is useful as an oxidant for many functional groups (alcohols, phenols, and ethers) as well as C-H bonds, especially those that are benzylic.
Used as oxidimetric standard. Used as reagent for analysis, microanalysis of silver and oxidant redox titration. Olefin polymerization catalyst.
