[4-[Bis[p-(dimethylamino)phenyl]methylene]-2,5-cyclohexadien-1-ylidene]dimethylammonium chloride [CAS 548-62-9].
Gentian Violet contains not less than 96.0 percent and not more than 100.5 percent of gentian violet (C25H30ClN3), calculated on the anhydrous basis.
Identification—
A: Sprinkle about 1 mg on 1 mL of sulfuric acid: it dissolves in the acid with an orange or brown red color. When this solution is diluted cautiously with water, the color changes to brown, then to green, and finally to blue.
B: Dissolve about 20 mg in 10 mL of water, and add 5 drops of hydrochloric acid. To 5 mL of this solution add tannic acid TS drop wise: a deep blue precipitate is formed.
C: To the remainder of the solution prepared for Identification test B add about 500 mg of zinc dust, and warm the mixture: rapid de-colorization occurs. Place a drop of the decolorized solution adjacent to a drop of 6 N ammonium hydroxide on a filter paper: a blue color is produced at the zone of contact.
Water: not more than 7.5%.
Residue on ignition: not more than 1.5%.
Alcohol-insoluble substances— Boil 1.0 g, accurately weighed, with 50 mL of alcohol under a reflux condenser for 15 minutes, filter through a tarred filtering crucible, wash the residue on the filter with hot alcohol until the last washing is not colored violet, and dry the crucible at 105 for 1 hour: not more than 1.0% of insoluble residue remains.
Arsenic— The limit is 0.001%.
Lead—The limit is 0.003%.
Zinc—
Zinc standard stock solution— Transfer about 1 g of zinc, accurately weighed, to a 1000-mL volumetric flask, add 50 mL of nitric acid, and mix to dissolve. Dilute with water to volume, and mix.
Standard preparation— Dilute the Zinc standard stock solution with water to obtain a Standard preparation containing 0.50 Ag of zinc per mL.
Test preparation— Weigh accurately 0.50 g of Gentian Violet in a suitable tarred crucible. Place in a low-temperature plasma ashing apparatus, and ash until a constant weight is attained. Pipette 10 mL of 6 N nitric acid into the crucible, and heat to dissolve the ash. Transfer the solution to a 500-mL volumetric flask, dilute with water to volume, and mix. Prepare a reagent blank.
Procedure— Concomitantly determine the absorbance of the Standard preparation, the Test preparation, and the reagent blank at the zinc emission line at 213.9 nm, with a suitable atomic absorption spectrophotometer (see Spectrophotometry and Light-Scattering 851) equipped with a zinc lamp and an air–acetylene flame, using water as the blank. The absorbance of the Test preparation, corrected for that of the reagent blank, is not greater than the absorbance of the Standard preparation, similarly corrected (0.05%).
