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.

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%).
Chromatographic purity— Dissolve 10 mg in 10 mL of methanol to obtain the Test solution. Transfer 1.0 mL of Test solution to a 100-mL volumetric flask, dilute with methanol to volume, and mix (Diluted test solution). Apply 5 AL each of the Test solution and the Diluted test solution to a suitable thin-layer chromatographic plate (see Chromatography 621 ) coated with a 0.25-mm layer of octadecylsilanized chromatographic silica gel. Allow the spots to dry, and develop the chromatogram in a suitable chromatographic chamber with a solvent system consisting of the upper layer separated from a well-shaken mixture of water, butyl alcohol, and glacial acetic acid (100:80:20), until the solvent front has moved about three-fourths of the length of the plate. Remove the plate from the chamber, allow the solvent to evaporate, and visually locate the spots on the plate: the Test solution exhibits a principal spot and not more than one secondary spot which, if present in the chromatogram from the Test solution, is not more intense than the principal spot obtained from the Diluted test solution (1.0%).
Assay—
Transfer about 400 mg of Gentian Violet, accurately weighed, to a 300-mL conical flask, add 25 mL of water and 10 mL of hydrochloric acid, displace the air in the flask with carbon dioxide, and pass a stream of carbon dioxide through the flask during the assay. Add 50.0 mL of 0.1 N titanium trichloride VS, heat to boiling, and boil gently for 10 minutes, swirling the liquid occasionally. Cool the solution, add 5 mL of ammonium thiocyanate solution (1 in 10), and titrate with 0.1 N ferric ammonium sulfate VS until a faint red color is produced. Perform a blank determination (see Residual Titrations 541 ). Each mL of 0.1 N titanium trichloride is equivalent to 20.40 mg of C25H30ClN3.

Gentian Violet is also called Crystal Violet or Basic Violet #3, Methylrosanilinium Chloride that’s the name in BP, Ph. Eur. and Hexamethyl-p-Rosaniline Chloride.

IUPAC Name is 4-[(4-dimethylaminophenyl)-phenyl-methyl]-N,N-dimethyl-aniline

Barter

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.

They assign the credit of their hard work to your blessings
They keep you amused.

They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.

They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.

They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.

They offer you a small bribe as advance for booty, called lottery
They love to dream.

I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
