Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 358.47 g/mol gives Iloprost Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Iloprost Impurity 3 (CAS CATO-C4X-32023, C22H30O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
The molecular framework of Iloprost Impurity 3 (C22H30O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Iloprost Impurity 3 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.
