Lidocaine EP Impurity D CAS 7728-40-7 chemical structure

Description

Lidocaine EP Impurity D (CAS 7728-40-7) is a certified pharmaceutical impurity reference standard with the molecular formula C12H18N2O and a molecular weight of 206.28 g/mol.

Based on its molecular formula C12H18N2O, Lidocaine EP Impurity D contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), Lidocaine EP Impurity D meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
