Acriflavine is used to fluorescently label high molecular weight RNA molecules .
Excitation and emission wavelengths in various solvents :

• Methanol: λex = 424 nm; λem = 518 nm
• Ethanol: λex = 426 nm; λem = 524 nm
• Propanol: λex = 430 nm; λem = 512 nm
• Butanol: λex = 430 nm; λem = 526 nm
• Formamide: λex = 434 nm; λem = 524 nm
• Glycerol: λex = 432 nm; λem = 540 nm
• Water: λex = 416 nm; λem = 514 nm

Insoluble in ether, chloroform, and fixed oils. Utilized in fluorescence steady state measurements as a donor molecule (when paired with rhodamine 6G as the acceptor) to function as a pH sensor .
