Coumarin boronic acid (CBA) is a fluorescent probe that can be used to detect peroxynitrite , hypochlorous acid, and hydrogen peroxide.It reacts with peroxynitrite at an exponentially faster rate (k = 1.1 μM/s) than hydrogen peroxide (k =1.5 M/s) and moderately faster rate than hypochlorous acid. Peroxynitrite oxidizes CBA into the fluorescent product 7-hydroxycoumarin (COH), which displays excitation/emission maxima of 332/470 nm, respectively.
