Indacaterol Impurity 57 HCl CAS 312753-56-3(Free base) chemical structure

Description

CATO supplies Indacaterol Impurity 57 HCl (CAS 312753-56-3(Free base)), a pharmacopoeial impurity reference standard (molecular formula C13H19NHCl, MW 225.76 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Indacaterol Impurity 57 HCl (C13H19NHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 225.76 g/mol, it falls into the medium-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), Indacaterol Impurity 57 HCl 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.
