General description

1,7-Dimethyluric acid is an important metabolite of caffeine. Electrochemical oxidation of 1,7-dimethyluric acid was studied over a wide pH range of 2.2-10.3 at solid electrodes.

Application

1,7-Dimethyluric acid is the suitable reagent used for the simultaneous determination of plasma levels of theophylline and its metabolites without interference from caffeine or caffeine metabolites by HPLC.
