Chemical Structure
Description
Salbutamol Impurity 121 (C22H29NO4) contains a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Salbutamol Impurity 121 (CAS CATO-C4X-1176121), a pharmacopoeial impurity reference standard (molecular formula C22H29NO4, MW 371.47 g/mol) used for the identification and quantification of trace impurities in APIs.
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), Salbutamol Impurity 121 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.
