Quick Summary

Aniline blue is a synthetic organic dye that was discovered as a result of experiments with aniline and other reagents. It is a type of triphenylmethane dye, and while it produces a promising blue color, it has poor water solubility.12

The development of synthetic dyes, including aniline blue, was significantly influenced by advancements in understanding the structure of aromatic compounds like benzene. These discoveries led to the creation of various dye classes, expanding the range of colors and applications available for textiles and other materials.345

…resulted in the discovery of aniline blue, a promising new dye, although it had poor water solubility. From the molecular formulas of these dyes, Hofmann showed that aniline blue was fuchsine with three more phenyl groups (―C₆H₅), but the chemical structures were still unknown. In a careful study, the British…
