Chemical Structure

Relmapirazin impurity 45 CAS CATO-C4X-33345 chemical structure

Description

Relmapirazin impurity 45 (CAS CATO-C4X-33345) is a certified pharmaceutical impurity reference standard with the molecular formula C24H30N12O15 and a molecular weight of 726.57 g/mol.

Structurally, Relmapirazin impurity 45 (C24H30N12O15) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 726.57 g/mol, it falls into the high-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.

As a certified reference material (CRM), Relmapirazin impurity 45 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.
