Application

Trans-1,2-Cyclohexanediaminetetraacetic acid monohydrate, min. 98% (CyDTA), is a white fine crystalline powder primarily used as an analytical reagent and complexating agent for sodium. Its function as a multidentate ligand makes it an essential component in preparing lanthanide shift reagents and metal-chelate complexes. Furthermore, CyDTA plays a crucial role in the separation and determination of various compounds, including iron(III)-dimethyldithiocarbamate, manganese(II)-ethylenebisdithiocarbamate, and zinc(II)-ethylenebisdithiocarbamate, using sensitive capillary electrophoretic ultraviolet methods.
