Description

A dye named durazol blue has been suggested as a replacement for methyl blue in Lendrum’s MSB. It is unlikely to be this dye, and more likely to be another one named durazol blue 4R. Unfortunately, the dye named was not specifically identified and it is not clear which one is meant.

Compare the formula with other phthalocyanines.
