Chemical Structure
Description
CATO supplies Bisoprolol EP Impurity B Oxalate (CAS CATO-C4X-124732), a pharmacopoeial impurity reference standard (molecular formula C18H31NO4C2H2O4, MW 415.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Bisoprolol EP Impurity B Oxalate (C18H31NO4C2H2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 415.48 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 B Oxalate 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.
