Triarylmethane dyes can be grouped into families according to the nature of the substituents on the aryl groups. In some cases, the anions associated with the cationic dyes (say crystal violet) vary even though the name of the dye does not. Often it is shown as chloride. Methyl violet dyes Methyl violet … See more Triarylmethane dyes are synthetic organic compounds containing triphenylmethane backbones. As dyes, these compounds are intensely colored. They are produced industrially as dyes. See more The amine-containing dyes are often prepared from Michler's ketone or its diethylamino analogue. In this way, the third aryl group is readily differentiated. The See more • Zelyonka attack • Phthalein dye See more Where two of the aryl groups are bridged by a heteroatom, these triarylmethane compounds may be further categorized into acridines (nitrogen-bridged), xanthenes (oxygen-bridged), and thioxanthenes (sulfur-bridged). See more In addition to their dominant use as dyes, many of these dyes react reversibly with acid and base, and thus serve as pH indicators.
