Abstract
A spectral and polarographic study of bromazepam yielded pK a values of 2.5, 5.2 and 11.8, corresponding to protonation at the azomethine and pyridine nitrogen atoms, and deprotonation at the nitrogen atom in position 1, respectively. These acid-base equilibrium reactions are discussed with reference to the hydrolysis and complexing properties of this compound. An indirect analytical method, based on the complexation of bromazepam with Cu 2+ ions, has been investigated by differential pulse anodic stripping voltammetry.
