“…In the chemical field, Tiron is known for analytical applications, primarily as a chelating agent used in the determination of trace metals. For example, Tiron is used as a colorimetric reagent of various metal ions, among which are Fe 3+ , Al 3+ , and Ti 4+ , for the sequestration of Pb 2+ , spectrofluorimetric determination of Cu 2+ , and spectrophotometric detection of Th 4+ and Bi 3+ . − More recently, it has been proposed for uses in electrochemistry concerning the preparation of redox flow batteries or modified glass electrodes. , …”
