Chemical Structure

Difelikefalin Impurity 9 CAS 1024828-90-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 721.93 g/mol gives Difelikefalin Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Difelikefalin Impurity 9 (CAS 1024828-90-7), a pharmacopoeial impurity reference standard (molecular formula C39H59N7O6, MW 721.93 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Difelikefalin Impurity 9 (C39H59N7O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 721.93 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Difelikefalin Impurity 9 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.
