Analytical possibilities of pyridine-2-acetaldehyde benzoylhydrazone as a chromogenic reagent

With a view to the use of pyridine-2-acetaldehyde benzoylhydrazone is an analytical reagent, a study of the physical properties and fundamental solution chemistry of the complexes formed by PABH with Fe(II), Fe(III), Ni(II), Pd(II), V(V), Ti(IV), Hg(II), Mn(II), Zn(II), Bi(III), Co(II), Cu(II), Pb(II), and Ga(III) metal ions has been carried out. A critical comparison of pyridine-2-carbaldehyde and pyridine-2-acetaldehyde salicyloylhydrazones and pyridine-2-acetaldehyde benzoylhydrazone as analytical reagents is given.
