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.
