Plerixafor Impurity 37 CAS CATO-C4X-113337

Description

Compared with other compounds in its class, the molecular weight of 514.79 g/mol gives Plerixafor Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Plerixafor Impurity 37 (CAS CATO-C4X-113337), a pharmacopoeial impurity reference standard (molecular formula C29H54N8, MW 514.79 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Plerixafor Impurity 37 (C29H54N8) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
