1,7-Dimethyluric acid is a metabolite of caffeine produced by the action of xanthine oxidase on paraxanthine. It can be detected in urine as a biomarker of caffeine consumption.
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.
ChEBI: An oxopurine that is 7,9-dihydro-1H-purine-2,6,8(3H)-trione substituted by methyl groups at N-1 and N-7. It is a metabolite of caffeine and is often found in human urine samples.
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.
