Abstract
A quantitative spectrophotometric method has been developed for determining the impurity of isonaphthazarin in samples of tetraxolin. The relative error of determination is about 1.0% at a confidence probability of P = 0.95%. The procedure is recommended for the quantitative control of the possible impurity of isonaphthazarin in the parent substance of tetraxolin.
