Chemical Structure
Description
Bisoprolol EP Impurity R Hemifumarate (C13H21NO2C4H4O4) contains a steroid 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 Bisoprolol EP Impurity R Hemifumarate (CAS CATO-C4X-124745), a pharmacopoeial impurity reference standard (molecular formula C13H21NO2C4H4O4, MW 339.39 g/mol) used for the identification and quantification of trace impurities in APIs.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Bisoprolol EP Impurity R Hemifumarate 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.
