Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 504.49 g/mol gives Sarecycline impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Sarecycline impurity 7 (CAS CATO-C4X-27987, C23H28N4O9) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
The molecular framework of Sarecycline impurity 7 (C23H28N4O9) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Sarecycline impurity 7 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.
