New fuchsine is an organic compound with the formula [(H₂N(CH₃)C₆H₃)₃C]Cl. It is a green-colored solid that is used as a dye of the triarylmethane class. It is one of the four components of basic fuchsine, and one of the two that are available as single dyes. The other is pararosaniline. It is prepared by condensation of ortho-toluidine with formaldehyde. This process initially gives the benzhydrol 4,4'-bis(dimethylamino)benzhydrol, which is further condensed to give the leuco (colorless) tertiary alcohol [(H₂N(CH₃)C₆H₃)₃COH, which is oxidized in acid to give the dye.
