(R,R)-Indacaterol Impurity 25 CAS 753498-27-0

Description

The occurrence of (R,R)-Indacaterol Impurity 25 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, (R,R)-Indacaterol Impurity 25 (CAS 753498-27-0, C49H49N3O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, (R,R)-Indacaterol Impurity 25 (C49H49N3O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 775.93 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), (R,R)-Indacaterol Impurity 25 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.
