Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Iloprost Impurity 8.
CATO supplies Iloprost Impurity 8 (CAS CATO-C4X-32028), a pharmacopoeial impurity reference standard (molecular formula C24H34O5, MW 402.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C24H34O5, Iloprost Impurity 8 contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 402.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 8 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.
