Rizatriptan Impurity 14 CAS 110-95-2 chemical structure

Description

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.

Rizatriptan Impurity 14 (CAS 110-95-2) is a certified pharmaceutical impurity reference standard with the molecular formula C7H18N2 and a molecular weight of 130.23 g/mol.

The molecular framework of Rizatriptan Impurity 14 (C7H18N2) is characterized by an organic framework. 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.
