We report bromopyrogallol red (BPR) as an easily available dye for detection of copper and chloride with distinct visual color changes in DMSO/H2O (9:1 v/v). The chemosensor has a high chromogenic selectivity for Cu2+ over other cations with detection limit of 0.07 μg mL−1. The obtained complex of Cu2+ with BPR displayed ability to detect Cl− up to 0.79 μg mL−1 in DMSO/H2O (9:1 v/v) media over a large number of other anions. The linear dynamic ranges for the determinations of Cu2+ and Cl− were 0.53–14.60 and 6.00–36.00 μg mL−1, respectively. This receptor was successfully applied for the determination of Cl− and Cu2+ in water samples.

► The first receptor for detection of Cu2+ and Cl− through the same detection method in a single cell.
► Able to provide selective binding to Cl− in water (very few colorimetric receptors have this ability).
► Highly selective and sensitive for ‘naked-eye’ sensing of Cu2+ and Cl− in aqueous medium.
► Available commercially in excellent purity.
