Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 457.43 g/mol gives Omadacycline Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Omadacycline Impurity 37 (CAS CATO-C4X-285737) is a certified pharmaceutical impurity reference standard with the molecular formula C22H23N3O8 and a molecular weight of 457.43 g/mol.
The molecular framework of Omadacycline Impurity 37 (C22H23N3O8) is characterized by a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Omadacycline Impurity 37 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.
