Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 458.59 g/mol gives Methylprednisolone impurity 97 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Methylprednisolone impurity 97 (CAS CATO-C4X-191997, C27H38O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Methylprednisolone impurity 97 (C27H38O6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Methylprednisolone impurity 97 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.
