Limaprost Impurity 11 CAS CATO-C4X-214511

Description

Compared with other compounds in its class, the molecular weight of 385.49 g/mol gives Limaprost Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Limaprost Impurity 11 (CAS CATO-C4X-214511) is a certified pharmaceutical impurity reference standard with the molecular formula C22H34NaO4 and a molecular weight of 385.49 g/mol.

The molecular framework of Limaprost Impurity 11 (C22H34NaO4) is characterized by a steroid 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), Limaprost Impurity 11 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.
