Fuchsine (sometimes spelled fuchsin) or rosaniline hydrochloride is a magenta dye with chemical formula C 20 H 19 N 3 ·HCl. [1] [2] There are other similar chemical formulations of products sold as fuchsine, and several dozen other synonyms of this molecule. [1] It becomes magenta when dissolved in water; as a solid, it forms dark green crystals.

New fuchsine is an organic compound with the formula [(H 2 N(CH 3)C 6 H 3) 3 C]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. [ 1 ]
Triarylmethane dyes can be grouped into families according to the nature of the substituents on the aryl groups. In some cases, the anions associated with the cationic dyes (say crystal violet) vary even though the name of the dye does not.

The 1861 article describe's Bechamp's fuchsine as C 12 H 12 N 2 O, and the hydrochlorate C 12 H 12 N 2 O·HCL. Maybe their analysis was wrong, or what's seeming more likely, is "fuchsine" was used to refer to a range of similar compounds at that time. No facts I've seen contradict either proposed etymology yet; citing both still seems like a ...
