Pararosaniline, Basic Red 9, or C.I. 42500 is an organic compound with the formula [(H₂NC₆H₄)₃C]Cl. It is a magenta solid with a variety of uses as a dye.^[1] It is one of the four components of basic fuchsine. (The others are rosaniline, new fuchsine and magenta II.)^[2] It is structurally related to other triarylmethane dyes called methyl violets including crystal violet, which feature methyl groups on nitrogen.

It is prepared by the condensation of aniline and para-aminobenzaldehyde. Alternatively, it arises from the oxidation of 4,4'-bis(aminophenyl)methane in the presence of aniline.
