Triarylmethane dye

Triarylmethane dyes are synthetic organic compounds containing triphenylmethane backbones. As dyes, these compounds are intensely colored. They are produced industrially as dyes.Methyl violet 2BMethyl violet 6BMethyl violet 10BPararosanilineFuchsine (hydrochloride salt)New fuchsine (As chloride)Fuchsine acidPhenolphthaleinPhenol redChlorophenol redCresol redBromocresol purpleBromocresol greenMalachite greenBrilliant green (dye)Brilliant Blue FCF, a common food colorant.Victoria Blue BVictoria Blue FBRVictoria blue BOVictoria Blue FGAVictoria blue 4 RVictoria blue R Triarylmethane dyes are synthetic organic compounds containing triphenylmethane backbones. As dyes, these compounds are intensely colored. They are produced industrially as dyes. 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 have dimethylamino groups at the p-positions of two aryl groups. Fuchsine dyes have primary or secondary amines (NH2 or NHMe) functional groups at the p-positions of each aryl group. Phenol dyes have hydroxyl groups at the p positions of at least two aryl groups.
