Description
CATO supplies rac-Formoterol EP Impurity H (Mixture) (CAS 2514947-17-0), a pharmacopoeial impurity reference standard (molecular formula C26H30N2O4, MW 434.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, rac-Formoterol EP Impurity H (Mixture) (C26H30N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 434.54 g/mol, it falls into the moderately-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), rac-Formoterol EP Impurity H (Mixture) 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.
