Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 456.89 g/mol gives Difloxacin-D3 Hydrochloride Hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Difloxacin-D3 Hydrochloride Hydrate (CAS CATO-CCAD301258), molecular formula C21H16D3F2N3O3HClH2O and molecular weight 456.89 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Difloxacin-D3 Hydrochloride Hydrate (C21H16D3F2N3O3HClH2O) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Difloxacin-D3 Hydrochloride Hydrate 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.
