Bisoprolol Impurity 78 CAS 2226263-67-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bisoprolol Impurity 78.

Bisoprolol Impurity 78 (CAS 2226263-67-6) is a certified pharmaceutical impurity reference standard with the molecular formula C15H22O4 and a molecular weight of 266.33 g/mol.

Bisoprolol Impurity 78 (C15H22O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Bisoprolol Impurity 78 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.
