Sodium diethyldithiocarbamate trihydrate is widely used as a vulcanization accelerator in the rubber industry. It helps in the process of converting natural or synthetic rubber into more durable materials by speeding up the curing process, which enhances the rubber's strength and elasticity. In addition, it serves as a chelating agent in analytical chemistry, where it binds to metal ions to form stable complexes, facilitating the detection and quantification of metals in various samples. It is also utilized in agriculture as a fungicide and pesticide, protecting crops from fungal infections and pest infestations. Furthermore, it finds application in water treatment processes to remove heavy metals from wastewater by forming insoluble complexes that can be easily filtered out. Additionally, it is employed in the mining industry as a collector in froth flotation processes to enhance the separation of valuable minerals from ores.
