Chemical Structure

Lidocaine Impurity 43 CAS CATO-C4X-167943 chemical structure

Description

Based on its molecular formula C14H19N3, Lidocaine Impurity 43 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a process- or degradation-related impurity, Lidocaine Impurity 43 (CAS CATO-C4X-167943, C14H19N3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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.
