Used in electroplating processes to produce corrosion-resistant coatings on metals, especially in aerospace and automotive industries. Employed in the preparation of cadmium telluride (CdTe) solar cells, where it enhances the efficiency and performance of photovoltaic devices. Serves as a catalyst or reagent in organic synthesis, particularly in the production of specialty chemicals and pigments. Utilized in laboratories for the detection and analysis of certain sulfides and in the formulation of cadmium-based compounds. Also applied in the manufacturing of phosphors for certain types of display technologies and fluorescent lamps. Due to its toxicity, handling requires strict safety and environmental controls.
