Biochemical Assay Reagents Drug Metabolite

1,7-Dimethyluric acid is an N-methylated uric acid and purine derivative, as well as a caffeine metabolite. When 1,7-Dimethyluric acid is acted upon by peroxidase in the presence of H2O2, it follows the same oxidation pathway to generate a UV-absorbing intermediate, which decays via first-order kinetics. 1,7-Dimethyluric acid can adsorb onto pyrolytic graphite electrodes, but not onto glassy carbon electrodes or platinum electrodes. The N-methylation modification of its pyrimidine ring prevents ring contraction of the diol intermediate, and no NMR evidence of O-alkylation is observed during propylation under the test conditions .

Cat. No.: HY-W127790
CAS No.: 52746-49-3
Bathophenanthrolinedisulfonic acid disodium is an iron ion chelator that serves as a colorimetric reagent for iron ion detection. Bathophenanthrolinedisulfonic acid disodium forms stable, strong complexes with Fe 2+ and Fe 3+, and each complex exhibits reversible redox behavior. Bathophenanthrolinedisulfonic acid disodium can act as a ligand to form water-soluble ruthenium catalysts, which promote the hydrogenation of the ketone group in levulinic acid to produce γ-valerolactone. When Bathophenanthrolinedisulfonic acid disodium and its iron complex are incorporated into a polymer-modified electrode, rapid color change from red to transparent occurs during potential cycling .
