|Section2= |Section3= }} Fuchsine (sometimes spelled fuchsin) or rosaniline hydrochloride is a magenta dye with chemical formula C20H19N3·HCl.〔("Basic chemical data" ). ''Discovery Series'' online database, Developmental Therapeutics Program, U.S. National Institutes of Health. Retrieved on 2007-10-08.〕〔Goyal, S.K. ("Use of rosaniline hydrochloride dye for atmospheric SO2 determination and method sensitivity analysis" ). ''Journal of Environmental Monitoring'', 3, 666–670, . Retrieved on 2007-10-08.〕 There are other similar chemical formulations of products sold as fuchsine, and several dozen other synonyms of this molecule.〔 It becomes magenta when dissolved in water; as a solid, it forms dark green crystals. As well as dying textiles, fuchsine is used to stain bacteria and sometimes as a disinfectant. In the literature of biological stains the name of this dye is frequently misspelled, with omission of the terminal -e, which indicates an amine.〔Baker JR (1958) Principles of Biological Microtechnique. London: Methuen.〕 American and English dictionaries (Webster's, Oxford, Chambers, etc.) give the correct spelling, which is also used in the literature of industrial dyeing.〔Hunger K (2003) Industrial Dyes. Chemistry, Properties, Applications. Weinheim: wiley-VHC.〕 It is well established that production of fuchsine results in development of bladder cancers by production workers. Production of magenta is listed as a circumstance known to result in cancer. ==History== Fuchsine was first prepared by August Wilhelm von Hofmann from aniline and carbon tetrachloride in 1858. François-Emmanuel Verguin discovered the substance independently of Hofmann the same year and patented it. Fuchsine was named by its original manufacturer Renard frères et Franc,〔Béchamp, M. A.

''ARTFL Project: 1913 Webster's Revised Unabridged Dictionary''. Retrieved on 2007-09-25〕 An 1861 article in ''Répertoire de Pharmacie'' said that the name was chosen for both reasons.〔Chevreul, M.
