A Deferasirox Derivative That Acts as a Multifaceted Platform for the Detection and Quantification of Fe3+

Here, we report that ExSO3H, a synthetically accessible, water-soluble, non-toxic derivative of the clinical iron chelator deferasirox, acts as colorimetric chemosensor permits detection and quantification Fe3+ in aqueous samples at pH 2–5. In addition, observed fluorescent turn-on response was produced when this allowed to interact with human serum albumin (HSA). This fluorescence quenched presence Fe3+, thus allowing us monitor biologically important metal cation via two independent methods.
