Pyranine (hydrate)

Pyranine (HPTS; Solvent Green 7) hydrate is a pH-sensitive fluorescent indicator. Pyranine hydrate acts as a class of fluorescent chemosensor for the Cu+ ion. Pyranine hydrate is used as a coloring agent, biological stain, optical detecting reagent, and pH indicator (Ex/Em = 450/510 nm) [1][2][3].
