Chemical Structure

Ibandronic Impurity 26 CAS CATO-C4X-224426 chemical structure

Description

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.

Ibandronic Impurity 26 (CAS CATO-C4X-224426) is a certified pharmaceutical impurity reference standard with the molecular formula C9H23NO7P2 and a molecular weight of 319.23 g/mol.

The molecular framework of Ibandronic Impurity 26 (C9H23NO7P2) is characterized by an amide group, a phosphate ester group, a carboxylic acid 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.

As a certified reference material (CRM), Ibandronic Impurity 26 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.
