Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.29 g/mol gives Bisoprolol EP Impurity L(Metoprolol EP Impurity C) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bisoprolol EP Impurity L(Metoprolol EP Impurity C) (CAS 29122-74-5) is a certified pharmaceutical impurity reference standard with the molecular formula C13H19NO3 and a molecular weight of 237.29 g/mol.
Bisoprolol EP Impurity L(Metoprolol EP Impurity C) (C13H19NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
CATO manufactures Bisoprolol EP Impurity L(Metoprolol EP Impurity C) 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.
