The staining of amyloid is far from specific and because of the lack of a marked color variation from other tissue components minimal amyloid deposits may be missed, especially in rectal biopsies Methyl violet 2B (IUPAC name: N - (4- (bis (4- (dimethylamino)phenyl)methylene)cyclohexa-2,5-dien-1-ylidene)methanaminium chloride) is a green powder which is soluble in water and ethanol but not in xylene. It appears yellow in solution of low pH (~0.15) and changes to violet with pH increasing toward 3.2. Methyl violet 10B Low pH color Transition pH range; Gentian violet (Methyl violet 10B) yellow: 0.0–2.0: Leucomalachite green (first transition) yellow: 0.0–2.0: Leucomalachite green (second transition) green: 11.6–14: Thymol blue (first transition) red: 1.2–2.8 Methyl violet, for microscopy (Bact., Bot., Hist.), indicator (pH 0.1-2.0), mixture of polymethylated pararosaniline hydrochlorides, fits were yielded with Langmuir and Redlich-Peterson isotherms. The methyl violet biosorption was strongly dependent solution pH and percentage dye removal became significant above pH 7, which was slightly higher than the pH(PZC) of the sawdust material. In addition, various thermodynamic parameters, such as DeltaG degrees, Methyl violet is a common pH indicator; it turns yellow at 0.1 pH and violet at 2.7 pH.
