Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 153.18 g/mol gives Carteolol Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carteolol Impurity 29 (CAS 23674-56-8) is a certified pharmaceutical impurity reference standard with the molecular formula C8H11NO2 and a molecular weight of 153.18 g/mol.
Carteolol Impurity 29 (C8H11NO2) contains an amino-acid-derived structure, 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 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 Carteolol Impurity 29 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.
