Patent Blue V sodium is a synthetic dye belonging to the triarylmethane class, commonly used as a food coloring additive and in histology as a stain for biological tissues. Its chemical structure features a central carbon bonded to two diethylaminophenyl groups and a sulfonated hydroxybenzene ring, which confer its vivid blue color and water solubility.
