Used as a precursor in the synthesis of samarium-containing materials for research in luminescent compounds and catalysis. Employed in the preparation of specialty glasses and ceramics where controlled samarium doping is required. Serves as a source of Sm³⁺ ions in studies of lanthanide coordination chemistry. Also utilized in the development of optical sensors and in some solid-state devices due to its ionic conductivity when dehydrated. Common in academic and industrial labs for exploring new bromide-based ionic conductors.
