Coumarin boronic acid pinacolate ester (CBE) is a more soluble form of coumarin boronic acid that can be used to detect peroxynitrite , hypochlorous acid, and hydrogen peroxide. Peroxynitrite oxidizes CBE into the fluorescent product 7-hydroxycoumarin (COH), which displays excitation/emission maxima of 332/470 nm, respectively.
