Sodium diethyldithiocarbamate trihydrate is widely used as a vulcanization accelerator in the rubber industry, enhancing the speed and efficiency of the vulcanization process to produce durable rubber products. In analytical chemistry, it serves as a chelating agent for the extraction and determination of metal ions, particularly copper, nickel, and cobalt, due to its strong complexing properties. It is also employed in wastewater treatment to remove heavy metals by forming insoluble complexes that can be easily separated. Additionally, this compound finds application in agriculture as a fungicide and pesticide, helping to protect crops from fungal infections and pests. In the pharmaceutical industry, it is used in the synthesis of certain drugs and as a stabilizer in formulations. Its ability to act as an antioxidant makes it useful in preventing the degradation of various materials exposed to oxidative conditions.
