The behaviour of benzoquinoneN-chloroimines under neutral, acidic, and basic conditions has been studied. Although these compounds are stable under neutral conditions they are hydrolysed in acidic solution to the corresponding benzoquinone derivatives. In the presence of base and alcohols, they are reduced to benzoquinoneimines. Kinetic investigation of the reaction suggested an ionic mechanism,
According to the present invention, phenols may be detected using an electrochemical sensor comprising a final compound, a working electrode and an electrolyte in contact with the working electrode, wherein the first compound operatively undergoes a redox reaction at the working electrodes to form a second compound which operatively reacts in situ with the phenol, wherein said redox reaction has a detectable redox couple and wherein the sensor is adapted to determine the electrochemical response of the working electrode to the consumption of said second compound on reaction with the phenol. The phenol may be, for example, cannabinoid or a catechin compound.
