Ibrutinib Impurity N2 CAS 43191-23-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ibrutinib Impurity N2.

CATO supplies Ibrutinib Impurity N2 (CAS 43191-23-7), a pharmacopoeial impurity reference standard (molecular formula C12H12N2, MW 184.24 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ibrutinib Impurity N2 (C12H12N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
