Crystal violet or gentian violet, also known as methyl violet 10B or hexamethyl pararosaniline chloride, is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria.
What is Gentian Violet (Crystal Violet)? Gentian Violet is a primary dye that is used for the purpose of Gram Staining. It is a triarylmethane dye which is also known as Crystal violet.
When the Gram-positive cells and Gram-negative cells are saturated with crystal violet (first step of the Gram stain), they become purple. When Gram's iodine is applied to the cells, it causes the crystal violet to adhere firmly in the thick peptidoglycan layer of Gram-positive cell walls.
Primary Stain (Crystal Violet) It is an intensely purple-colored organic compound chemically called triphenylmethane dye. It is also known as hexamethyl pararosaniline chloride or methyl violet 10B or gentian violet.
Crystal violet (gentian violet) is a sensitive stain that reacts with epithelial cells and other proteins of latent print residue transferred upon surface contact. Crystal violet is usually very effective on surfaces that readily hold the deposited sebum, such as the adhesive side of tape.
Crystal violet (CV) is a cationic triphenyl methane dye chemically known as hexamethyl pararosaniline chloride. It is a highly demanded industrial raw material used in far-reaching industrial and...

Thus, commonly used basic dyes such as basic fuchsin, crystal violet, malachite green, methylene blue, and safranin typically serve as positive stains. On the other hand, the negatively charged chromophores in acidic dyes are repelled by negatively charged cell walls, making them negative stains.
Gentian violet ( (GV) hexamethyl pararosaniline, also known as crystal violet, methyl violet) is a triphenylmethane dye with anti-bacterial, anti-fungal, anti-helminithic, anti-trypanosomal, anti-angiogenic and anti-tumor properties.
Crystal Violet is a triarylmethane dye commonly used to distinguish between gram-positive and gram-negative bacteria based on their cell wall properties. It is also utilized in cell viability assays to measure living cells by binding to ribose molecules and proteins in the nucleus.
