Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 245.66 g/mol gives Labetalol Impurity 63 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Labetalol Impurity 63 (CAS CATO-C4X-246663), a pharmacopoeial impurity reference standard (molecular formula C10H11NO4HCl, MW 245.66 g/mol) used for the identification and quantification of trace impurities in APIs.
Labetalol Impurity 63 (C10H11NO4HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), Labetalol Impurity 63 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.
