5(6)-Carboxy-2',7'-dichlorofluorescein (CDCF)

5-(and-6)-carboxy-2′,7′-dichlorofluorescein is similar to carboxyfluorescein (51013), but has lower pKa. It is useful for detecting pH in more acidic environment.


  • pKa = 4.8
  • λExλEm = 504/529 nm
  • ε= 90,000
  • Cell permeability: Membrane impermeant
  • Cellular localization:Fluid phase tracer
  • Colors: Green
  • Orange solid soluble in DMSO and pH>6 buffers
  • Store at room temperature and protect from light, especially in solution


Also see the membrane-permeant compound dichlorofluorescein diacetate (51016).
