Chemical Structure

N-oxide Lomeprol Impurity 8 CAS CATO-C4X-18208 chemical structure

Description

The occurrence of N-oxide Lomeprol Impurity 8 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-oxide Lomeprol Impurity 8 (CAS CATO-C4X-18208), a pharmacopoeial impurity reference standard (molecular formula C17H22I3N3O9, MW 793.08 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H22I3N3O9, N-oxide Lomeprol Impurity 8 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 793.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
