Description
As a certified reference material (CRM), Mesalazine Impurity 56 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.
Mesalazine Impurity 56 (CAS CATO-C4X-132456) is a certified pharmaceutical impurity reference standard with the molecular formula C7H6N2O4 and a molecular weight of 182.13 g/mol.
Structurally, Mesalazine Impurity 56 (C7H6N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 182.13 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
