Daclatasvir Impurity 9 CAS CATO-C4X-18489

Description

Compared with other compounds in its class, the molecular weight of 424.54 g/mol gives Daclatasvir Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Daclatasvir Impurity 9 (CAS CATO-C4X-18489), a pharmacopoeial impurity reference standard (molecular formula C26H28N6, MW 424.54 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Daclatasvir Impurity 9 (C26H28N6) 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. 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.
