Using Capsaicin Modified Multiwalled Carbon Nanotube Based Electrodes and p-Chloranil Modified Carbon Paste Electrodes for the Determination of Amines: Application to Benzocaine and Lidocaine

Abstract:

The utilization of the capsaicin modified carbon nanotube modified basal-plane pyrolytic graphite electrode or p-chloranil modified carbon paste electrodes are presented for the determination of pharmaceutical compounds containing amine functionality, such as benzocaine and lidocaine. In detection of benzocaine at a capsaicin modified electrode, the guaiacol functional group is irreversibly electrochemically oxidized to form the o-quinone derivative which then undergoes nucleophilic attack by...
