Used primarily in research and laboratory settings, it serves as a source of cadmium ions in various chemical reactions and studies. It is often employed in electrochemical applications, such as in the preparation of cadmium-based electrodes or in the study of electroplating processes. Additionally, it can be utilized in the synthesis of other cadmium compounds or as a reagent in analytical chemistry for testing and analysis purposes. Due to its hygroscopic nature, it requires careful handling and storage to maintain its effectiveness in these applications. As a cadmium compound, it is highly toxic and a strong oxidizer owing to the perchlorate anion; strict safety protocols must be followed to prevent exposure and fire hazards.
