Chemically reactive spin probes can be used as 'reporter' molecules to probe a local chemical environment. Such application usually involves the appearance or disappearance of an ESR signal, or the turning on or off of fluorescence from a nearby fluorophore. Verdazyls are stable heterocyclic radicals that have potential in this area. To further investigate this possibility, we report studies of aqueous verdazyl reactivity with various biologically important species such as ascobic acid, glutathione and superoxide.
