It is insoluble in water and soluble in ethanoland DMSO. Auramine O can be used to stain acid-fastbacteria (e.g. Mycobacterium, where it binds to the mycolic acidin its cell wall) in a way similar to Ziehl–Neelsen stain.[1]

WebThe 10, the dye molecule will transform into a colorless carbinol base positive holes are considered major oxidation species at low pH [42]. The results related to the photodegradation rate differed from while hydroxyl radicals are the predominant species at neutral or those of cationic dyes in the triphenylmethane/TiO2 system [43]. 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 dyes have … 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 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.
