1,7-Dimethyluric acid-d3 is the deuterium-labeled analogue of 1,7-dimethyluric acid, a metabolite of caffeine. The d3 isotopologue (three deuterium atoms) is intended for use as a stable-isotope reference standard in analytical workflows, particularly quantitative mass spectrometry and tracer studies. Molecular formula: C7H5D3N4O3; molecular weight: 199.18 g/mol.
- Deuterium-labeled internal standard for LC-MS quantitation.
- Three deuterium labels enable clear mass separation from unlabeled analyte.
- Suitable for metabolite identification and tracer studies.
- Provided as a high-purity research-grade standard; verify lot-specific purity.
- Packaged for small-scale analytical use (microgram to milligram quantities).
