Used as a catalyst in organic synthesis, particularly in the production of acrylic fibers and certain plastics. Serves as a precursor in the preparation of cadmium-containing nanomaterials and semiconductors. Employed in electroplating processes to deposit cadmium coatings for corrosion resistance. Also utilized in analytical chemistry for detecting sulfide ions due to its reactivity with sulfur compounds. Its use is limited in many applications due to the toxicity of cadmium, leading to strict handling and disposal requirements.
