Ketoprofen Impurity 59 CAS CATO-C4X-147159

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ketoprofen Impurity 59.

As a process- or degradation-related impurity, Ketoprofen Impurity 59 (CAS CATO-C4X-147159, C32H30O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Ketoprofen Impurity 59 (C32H30O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 510.58 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.

As a certified reference material (CRM), Ketoprofen Impurity 59 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.
