Pararosaniline Hydrochloride is an organic compound, It is a magenta solid and one of the four constituents of Basic fuchsin besides rosaniline, new fuchsine, and magenta II. Structurally, it is allied to other triarylmethane dyes, such as methyl violets, including crystal violet, which features methyl groups on nitrogen. It is prepared by the condensation of aniline with para-aminobenzaldehyde or from the oxidation of 4,4′-bis(aminophenyl)methane in the presence of aniline.

Pararosaniline hydrochloride is used as a dye for staining in histology, for colorimetric tests like the Schiff test, and for detecting sulfur dioxide.
Pararosaniline hydrochloride solution is typically magenta or deep red.
To prepare a Pararosaniline hydrochloride solution, dissolve the required amount of Pararosaniline hydrochloride powder in distilled water. The concentration will depend on your specific application. Stir until fully dissolved and filter if necessary to remove any undissolved particles.
Pararosaniline hydrochloride is soluble in water and ethanol. Its solubility in water allows it to be used effectively in aqueous staining solutions.
