Used as a precursor in the synthesis of cadmium-based nanomaterials, particularly cadmium sulfide and cadmium selenide quantum dots, which are applied in optoelectronic devices and solar cells. Serves as a catalyst or catalyst support in organic reactions, including esterification and polymerization processes. Employed in electroplating baths to deposit cadmium coatings that provide corrosion resistance to metals. Utilized in the preparation of cadmium oxide thin films for semiconductor and sensor applications. Also used in the production of cadmium pigments for ceramics, glass coloring, and artists' paints. Employed in analytical chemistry as a reagent for qualitative and quantitative analysis of certain anions.
