|Section2= |Section3= }} New fuchsine, (from German "fuchs", ''fox'') is an organic compound with the formula ()Cl. It is a magenta-colored solid that is used as a dye. It is one of the four components of basic fuchsine, and one of the two that are available as single dyes.〔Horobin RW, Kiernan JA (2002) Conn's Biological Stains, 10th ed. Oxford: BIOS.〕 The other is pararosaniline. It is prepared by condensation of N-methyltoluidine with xylidene in the presence of hydrochloric acid. ==Use as dye and stain== It is used to dye polyacrylonitrile, paper, and leather.〔Thomas Gessner and Udo Mayer "Triarylmethane and Diarylmethane Dyes" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim.〕 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.〔Lojda Z, Gossrau R, Schiebler TH (1979) Enzyme Histochemistry.
