7-Diethylamino-3-(4-isothiocyanatophenyl)-4-methylcoumarin (CPI) is a fluorescent labeling reagent that reacts covalently with amino groups. It is a isothiocyanate derivative of coumarin. It has a high quantum yield (0.75-0.78), long wavelength excitation, and high stability, which makes it ideally suited as fluorescent label for proteins. The quantum yield is little affected by the pH of solutions. Spectral Data: lambdaem = 396nm; lambdaem = 478nm. - Chemical. CAS: 107743-39-5. Formula: C21H20N2O2S. MW: 364.46.
