Description
1) A bright, blue synthetic triarylmethane dye. Aniline blue was first made from coal-tar derivatives by Girard and de Laire and patented in January 1861. The blue color is formed by heating Magenta in the presence of excess Aniline. Aniline blue is used as a dye and stain.
2) The sodium salt of the same compound is called water soluble aniline blue. Aniline Blue WS is used as in inks and dyes (Wool, nylon, Leather, and Paper).
