New fuchsine

New fuchsine, new fuchsin, Magenta III, Basic Violet 2, or C.I. 42520 (from German "fuchs", fox) is a magenta dye having chemical formula Template:Carbon22Template:Hydrogen24Template:Nitrogen3Template:Chlorine. It is one of the four components of basic fuchsine, and one of the two that are available as single dyes.[1] (The other is pararosaniline.) New fuchsine can be used for staining acid fast organism, e.g. by Ziehl-Neelsen stain, and for making Schiff's reagent. As a primary amine, the dye can be diazotized in the laboratory, and the resulting diazonium salt used as a trapping agent in enzyme histochemistry.[2]
