Used as a highly stable cesium source in organic synthesis, particularly in cross-coupling reactions where soluble and non-nucleophilic cesium ions are required. Its unique cage structure enhances solubility in polar solvents while maintaining thermal and chemical stability. Employed in the preparation of advanced materials, including pharmaceuticals and agrochemicals, due to its ability to facilitate difficult nucleophilic substitutions. Also finds use in catalysis and as a precursor in the synthesis of specialty boron-containing compounds for neutron capture therapy research.
