[7] The compound has been identified as a catalyst for the high pressure oxidative chlorination of methane to chloromethane with hydrochloric acid and oxygen.

[8] In Fluid Catalytic Cracking (FCC), lanthanum chloride enhances catalysts to convert heavy crude into valuable fuels like gasoline and diesel.

[9] Also used in the field of geology as a very dilute solution, which when combined with the proper acids can help identify small >1% Strontium content in powdered rock samples.

Lanthanum chloride also contributes to environmental remediation by promoting- the catalytic transformation of pollutants, such as nitrogen oxides (NOx), volatile organic compounds (VOCs), sulfur dioxide (SO₂), and phosphate ions, into less harmful products.

[10] It can also be commercially viable and significantly outperform conventional materials such as ion exchange resins, activated carbons, and iron oxides in water and wastewater treatment, especially for the removal of anionic pollutants.
