Methyl violet powder

Description

A blue-green powder that forms a deep violet aqueous solution. Methyl violet is a triphenylmethane dye that was synthesized in 1861 by Lauth. It has a very strong tinting strength and is used as a dye for Wood, Silk, and Paper. Methyl violet is also used in inks, as a biological stain, and as an acid-base indicator.
