Description
As a certified reference material (CRM), BPA Impurity 3 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.
BPA Impurity 3 (CAS CATO-C4X-31393) is a certified pharmaceutical impurity reference standard with the molecular formula C29H46BNO8 and a molecular weight of 547.49 g/mol.
Structurally, BPA Impurity 3 (C29H46BNO8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 547.49 g/mol, it falls into the moderately-high-molecular-weight range. 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.
