Medchemexpress LLC Febuxostat-d9 | 1246819-50-0 | MFCD21363615 | 98.7% | C16H7D9N2O3S | 10MG
Febuxostat-d9 is a deuterium-labeled analogue of febuxostat supplied as an isotopically labeled reference standard for analytical and research applications. It is intended for use as an internal standard in LC- or GC-MS assays and in studies of xanthine oxidase inhibition. The material is supplied with high isotopic enrichment and high chemical purity (≈98.7%, C16H7D9N2O3S, MW 325.43) for research use only.
- Deuterium-labeled internal standard for LC- or GC-MS quantification.
- Facilitates accurate quantification and compensation for matrix effects.
- High isotopic enrichment and purity for reliable analytical performance.
- Suitable for pharmacokinetic, metabolic, and bioanalytical studies.
- Provides a clear mass shift from the unlabeled analyte for MS separation.
Medchemexpress LLC Macitentan-d4 | 1258428-05-5 | 98.0% | C19H16D4Br2N6O4S | 10MG
Macitentan-d4 is a deuterium-labeled analog of macitentan intended for use as an isotope-labeled internal standard in analytical and research workflows, especially mass spectrometry-based quantitation for pharmacokinetic and metabolite studies.
