Abstract

Molar absorptivities of six catecholamines (CA) are determined from their reactions with hydrochloric acid, boric acid molybdic acid, germanium dioxide, iron (II)-citrate and zirconyl chloride. Significant linear correlations are obtained between emax and the number of ligands. emax of most of the (CA) investigated shows a significant correlation with the molecular connectivity indices of the side chains and pka values. A dimeric state is suggested for (CA) in 0.1 N hydrochloric acid medium.
