Product Application of Lanthanum(III) Chloride CAS#10099-58-8
Lanthanum(III) Chloride is a stable heterogeneous catalyst widely employed in various organic reactions. It is used in the solvent-free synthesis of substituted olefins via the Knoevenagel condensation, the one-pot preparation of 3,4-dihydropyrimidin-2(1H)-ones, and as a precursor for producing La/V co-doped TiO₂ nanoparticles through the sol-gel method.
