Ph of aniline
WebbMauveine. Mauveine, also known as aniline purple and Perkin's mauve, was one of the first synthetic dyes. [1] [2] It was discovered serendipitously by William Henry Perkin in 1856 while he was attempting to synthesise the phytochemical quinine for the treatment of malaria. [3] It is also among the first chemical dyes to have been mass-produced.
