Fuchsine base (monohydrochloride)

Fuchsine base (Magenta base; Basic Fuchsin) monohydrochloride is a triaminotriphenylmethane dye. Fuchsine base monohydrochloride has anesthetic, bactericidal and fungicidal properties. Fuchsine base monohydrochloride can be used for the staining of collagen, muscle, mitochondria and tuberculosis. Fuchsine base monohydrochloride is commonly used as a counterstain in Gram staining[1][2].
