Medchemexpress LLC Uric acid-13C,15N3 | 2421217-23-2 | 99.2% | 1 MG
Uric acid-13C,15N3 is the 13C-labeled and 15N-labeled uric acid. Uric acid is a scavenger of oxygen radicals and a significant antioxidant that helps maintain blood pressure stability and antioxidant stress. It can remove reactive oxygen species (ROS) like singlet oxygen and peroxynitrite, thereby inhibiting lipid peroxidation. Stable heavy isotopes have been incorporated into drug molecules as tracers for quantitation during drug development. Deuteration can affect pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
