This dye and water blue are the constituents of aniline blue WS Any of the three will generally be found suitable for staining collagen in Masson's trichrome and Mallory's method for connective tissue. It is a constituent of Mann's methyl blue eosin method.

Note that Conn and Gurr give different structural formulae for this dye. It may well be that two different compounds are sold under this name. Note also that Gurr does not give CI numbers or names, and these data are reliable only for the Conn formula.
