Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 353.45 g/mol gives Bisoprolol Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Bisoprolol Impurity 22 (CAS 1447715-45-8, C19H31NO5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Bisoprolol Impurity 22 (C19H31NO5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Bisoprolol Impurity 22 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
