The ligand 2–Hydroxy–5–chlorobenzophenone oxime (HCBO) was developed as a new analytical reagent for the

gravimetric and spectrophotometric analysis of Cu(II) ion. In the pH range of 2.5 to 8.0 this reagent gives buff precipitates

with Cu(II). Job‘s method of continuous variation and Yoe and Jone‘s mole ratio method revealed the stoichiometry of the complex to be 1:2 [M:L].

The obeyence of Beer‘s law was studied and the molar absorptivity and Sandell‘s sensitivity were calculated. The reagent and its complex have

been characterized by elemental analysis and IR spectra. The reagent has been used for the determination of Copper content in Brass alloy.
