Chemical Structure

Lamotrigine Impurity 14 CAS CATO-C4X-167214 chemical structure

Description

The occurrence of Lamotrigine Impurity 14 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Lamotrigine Impurity 14 (CAS CATO-C4X-167214), a pharmacopoeial impurity reference standard (molecular formula C9H7Cl2N5O, MW 272.09 g/mol) used for the identification and quantification of trace impurities in APIs.

Lamotrigine Impurity 14 (C9H7Cl2N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
