Abstract	A new analytical reagent 8-(p-ethylbenzenesulfonamido)quinoline(EBSQ) has been synthesized, and identified its structure. EBSQ forms copper chloroform-soluble complex in a basic solution (pH = 7.5∼10.5). The other optimum conditions for the spectrophotometric study of Cu-EBSQ have been established at 380 mμ. Beer's law is followed in the concentration range of 0~44.5 μg per 10 ml of chloroform. The composition of complex has been found to be Cu(EBSQ-H)2and the over-all instability constant is calculated to be 1.22×10-7. The absorption coefficient of the Cu(EBSQ-H)2 complex is ε = 15,800.
