Pyranine is a hydrophilic, pH-sensitive fluorescent dye from the group of chemicals known as arylsulfonates.[2][3] Pyranine is soluble in water and has applications as a coloring agent, biological stain, optical detecting reagent, and a pH indicator.[4][5] Pyranine is also used in yellow highlighters to provide their characteristic fluorescence and bright yellow-green colour. It is also found in some types of soap.[6]
