5-(and-6)-carboxy-2,7-dichlorofluorescein is similar to carboxyfluorescein, but has lower pKa. It is useful for detecting pH in more acidic environment. Also see the membrane-permeant compound dichlorofluorescein diacetate. pKa = 4.8 lambdaEx/lambdaEm = 504/529 nm epsilon= 90,000 Orange solid soluble in DMSO and pH>6 buffers Store at room temperature and protect from light, especially in solution C21H10Cl2O7 MW: 445 [111843-78-8]
