Basic fuchsin also known as Fuchsine or Rosaniline hydrochloride is a fluorescent triphenylmethane dye composed of rosaniline, magenta II, pararosaniline and new fuchsine. It is an amine salt and has three amine groups, two primary amines and a secondary amine. It occurs as a dark green powder but becomes magenta when dissolved in water.
The fuchsin dye is the most commonly employed in staining operations. It’s utilised in Gomori’s aldehyde-fuchsin method, periodic acid Schiff method, and Endo media to distinguish E.coli and K.aerogenes bacteria. Basic fuchsin is also employed as a counter-stain in Gram’s staining.
