Fuchsine

Fuchsine or rosaniline hydrochloride is a magenta dye with chemical formula C₁₉H₁₇N₃·HCl and CAS number 569–61–9. It becomes magenta when dissolved in water; as a solid, it forms dark green crystals. Its inventor, the 19th century French company Renard, named the dye after the German translation of the company's name, fuchs (fox).

As well as dying textiles, fuchsine is used to stain bacteria and sometimes as a disinfectant.
