Resumo(s):	A carboxylic acid azo dye, Dabcyl, was synthesized and evaluated as a colorimetric chemosensor for metal cations with biological and environmental importance. The dye was prepared in high yield and characterized by 1H and 13C NMR and UV-vis absorption spectroscopies. A preliminary chemosensing study showed that Dabcyl displayed a marked color change, from light yellow to pink, for Hg2+, Fe2+, Pd2+, Sn2+ and Al3+ in acetonitrile solution. Consequently, spectrophotometric titrations were carried out for this dye with selected cations, which clearly indicated that Dabcyl has potential application as a chromogenic probe for the cations under study with remarkable sensitivity and a marked color change.
