Description
As a certified reference material (CRM), Oseltamivir-d5 Phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Oseltamivir-d5 Phosphate (CAS 204255-11-8 (unlabeled)), molecular formula C16H23D5N2O4H3O4P and molecular weight 415.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Oseltamivir-d5 Phosphate (C16H23D5N2O4H3O4P) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
