This dye is not used in histology, but is an important compound historically, as it was the first synthetic dye to be made from aniline. Its accidental preparation by a student, named William Henry Perkin, eventually led to the modern chemical dye industry, thus indirectly to the way we practice histotechnology today.

In 1967, Edward Gurr was given a small sample of mauveine which was 111 years old at the time, i.e. produced in 1856 the same year Perkin first made it. The information in the chart to the left is based on that sample, and on the structural formula as given by Gurr, above. Due to the small amount of dye available the data is suspect.

 

The structural formula was fully determined in 1994, and it was shown that mauveine is actually a mixture of two compounds, mauveine A and mauveine B above. Instructions have also been published so that the dye can be made in small quantities (Scaccia, Coughlin and Ball).
