Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 404.50 g/mol gives Salbutamol Impurity 173 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Salbutamol Impurity 173 (CAS CATO-C4X-1176173, C22H32N2O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Salbutamol Impurity 173 (C22H32N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 Salbutamol Impurity 173 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.
