Ammonium pyrrolidinedithiocarbamate is widely used as a chelating agent in analytical chemistry, particularly for the extraction and determination of trace metals. It forms stable complexes with various metal ions, making it valuable in environmental testing to detect heavy metals in water, soil, and air samples. In industrial applications, it is employed in the purification processes of metal ores and in the removal of metal contaminants from wastewater. Additionally, it serves as a reagent in spectrophotometric analysis for quantifying metal concentrations in biological and chemical samples. Its ability to bind selectively to specific metals also makes it useful in research laboratories for studying metal-ligand interactions and in the development of metal-based pharmaceuticals.
