Glycopyrronium Bromide EP Impurity O CAS 618-88-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Glycopyrronium Bromide EP Impurity O.

Glycopyrronium Bromide EP Impurity O (CAS 618-88-2) is a certified pharmaceutical impurity reference standard with the molecular formula C8H5NO6 and a molecular weight of 211.13 g/mol.

The molecular framework of Glycopyrronium Bromide EP Impurity O (C8H5NO6) is characterized by an amino-acid-derived structure, an amide 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Glycopyrronium Bromide EP Impurity O 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.
