Crystal violet, also known as Basic Violet 3 or Gentian Violet, is a basic, cationic aminoarylmethane dye. It is the N-hexamethylated derivative of pararosaniline and bears a lipophilic cation. It is primarily used in bacteriology and microscopy as the primary stain in Gram staining to classify and distinguish between Gram-positive and Gram-negative bacteria. It is indicator grade, exhibiting a color transition from yellow-green in acidic conditions to blue-violet in basic conditions. It also possesses antibacterial and antifungal properties.Crystal violet is mainly used in Gram staining and its variants, and for staining amyloid, bacterial components, and vascular plant tissues.It is used in polychrome staining of epoxy resin sections, viability staining of cultured neurons, and confocal optical sectioning to analyze meiotic structures.It is also employed in the acridine orange-crystal violet staining of intracellular bacteria, microsporidian spores, and cytological smears.
