The Cerium chloride, with the CAS registry number 7790-86-5, is also known as Cerous chloride. It belongs to the product categories of Inorganics; Ce (Cerium) Compounds; Classes of Metal Compounds; Transition Metal Compounds; Metal Halide. Its EINECS registry number is 232-227-8. This chemical's molecular formula is CeCl₃ and molecular weight is 246.48. What's more, its systematic name is called Cerium(3+) trichloride. It can be made by dehydration of the hydrate either by slowly heating to 400 °C with 4-6 equivalents of ammonium chloride under high vacuum, or by heating with an excess of thionyl chloride for three hours. Cerium(III) chloride can be used as a starting point for the preparation of other cerium salts, such as the Lewis acid, cerium(III) trifluoromethanesulfonate, used for Friedel-Crafts acylations. It is also used itself as a Lewis acid, for example as a catalyst in Friedel-Crafts alkylation reactions.

Physical properties about Cerium chloride are: (1)Density: 3.97 g/cm³; (2)Flash Point: 1727 °C; (3)Melting point: 848 °C(lit.); (4)Boiling Point: 1727 °C at 760 mmHg.

Uses of Cerium chloride: it is used to produce other chemicals. For example, it can react with sodium borohydride to get allylic alcohol.
