Uses of Lanthanum(III) chloride:
Lanthanum(III) chloride can be used to remove phosphates in swimming pools, which helps prevent algae growth. It is also used in biochemical research to block the activity of divalent cation channels, mainly calcium channels. Doped with cerium, it is used as a scintillator material. It is used as a mild Lewis acid to perform chemical reactions that usually require acidic conditions, such as converting aldehydes to acetals, under nearly neutral conditions.
The toxicity data of Lanthanum(III) chloride are as follows:
