Spectrophotometric determination of pindolol via charge transfer complex

ABSTRACT

Two Pi acceptors, tetracyanoethylene [TCNE], P-chloranilic acid [P-CA] and one epsilon-acceptor, iodine, were used for assay of pindolol by the formation of charge-transfer complexes having intense absorption b and s in the visible region of the spectrum. The molecular ratio of the reactants and experimental conditions, leading to intense charge-transfer b and s, were studied. Compared with the official method, the results of the tablet assays were of equal accuracy [t- test] and reproducibility [f-test]
