A novel and efficient colorimetric chemosensor for detection and determination of biologically important ions in DMSO/H2O media using bromo pyrogallol red chemosensors with analytical applications.

An efficient colorimetric chemosensor with bromo pyrogallol red (BPR) as an easily available dye demonstrated a high chromogenic selectivity for Fe(3+) over other cations with detection limit of 5.1 μmol L(-1). The complex of Fe(3+) with BPR displayed ability to detect of up to 4.

Colorimetric detection of copper and chloride in DMSO/H₂O media using bromopyrogallol red as a chemosensor with analytical applications.

We report bromopyrogallol red (BPR) as an easily available dye for detection of copper and chloride with distinct visual color changes in DMSO/H(2)O (9:1 v/v). The chemosensor has a high chromogenic selectivity for Cu(2+) over other cations with detection limit of 0.07 μg mL(-1).
