Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 390.97 g/mol gives Plerixafor Impurity 46 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Plerixafor Impurity 46 (CAS 128495-30-7) is a certified pharmaceutical impurity reference standard with the molecular formula C17H30N4O2SHCl and a molecular weight of 390.97 g/mol.
Structurally, Plerixafor Impurity 46 (C17H30N4O2SHCl) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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 390.97 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), Plerixafor Impurity 46 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.
