Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 189.17 g/mol gives Metronidazole-hydroxy D2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Metronidazole-hydroxy D2 (CAS 2196180-19-3) is a high-purity analytical reference standard with the molecular formula C6H7D2N3O4 and a molecular weight of 189.17 g/mol.
The molecular framework of Metronidazole-hydroxy D2 (C6H7D2N3O4) is characterized by deuterium isotope labeling, an amino-acid-derived structure, an amide 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Metronidazole-hydroxy D2 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.
