Ceric ammonium nitrate

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.

You should be cautious while dealing with this chemical. If contact with combustible material, and may cause fire. And this chemical has risk of serious damage to eyes, and cause sensitization by inhalation.
