Chemical Structure

Irinotecan Impurity N1 CAS 1026078-50-1 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.

CATO supplies Irinotecan Impurity N1 (CAS 1026078-50-1), a pharmacopoeial impurity reference standard (molecular formula C11H20N2O2, MW 212.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H20N2O2, Irinotecan Impurity N1 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
