Crystal violet or methyl violet is used in many applications, including: As a pH indicator (yellow to violet with the transition at a pH = 1.6) In the medical community, it is the active ingredient in Gram's Stain, used to classify bacteria. The dye destroys cells and is used as a moderate-strength external the range from 0.0 to 1.6 is called the transition range. Methyl violet changes from yellow to blue-violet. The midpoint of this range, pH 0.80 - is where 50% of the methyl violet is still yellow, and 50% is now blue-violet.

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.
