Ceric ammonium nitrate(16774-21-3) is produced by dissolving Ce₂O₃ in hot concentrated HNO₃.

The Ceric ammonium nitrate, with the CAS registry number 16774-21-3 and EINECS registry number 240-827-6, has the systematic name of cerium(4+) tetranitrate-nitric acid (1:2) diammoniate. It is a kind of yellow-orange crystals, and belongs to the following product categories: Inorganics; Others; Oxidation; Synthetic Reagents. And the molecular formula of this chemical is CeN₈H₈O₆N₁₈. What's more, it is water-soluble, and widely used as an oxidising agent in organic synthesis and as a standard oxidant in quantitative analysis.

The physical properties of Ceric ammonium nitrate are as followings: (1)#H bond acceptors: 26; (2)#H bond donors: 8; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 392.1 Å².

The preparation of Ceric ammonium nitrate: The anion [Ce(NO₃)₆]^2- is generated by dissolving Ce₂O₃ in hot concentrated nitric acid. And the salt consists of the anion [Ce(NO₃)₆]^2- and a pair of NH⁴⁺ counter ions. The ammonium ions are not involved in the oxidising reactions of this salt. In the anion each nitrato group is chelated to the cerium atom in a bidentate manner.
