Chemical Structure

Nicotinamide impurity 19 CAS CATO-C4X-200019 chemical structure

Description

Nicotinamide impurity 19 (CAS CATO-C4X-200019) is a certified pharmaceutical impurity reference standard with the molecular formula C7H10N2O and a molecular weight of 138.17 g/mol.

The molecular framework of Nicotinamide impurity 19 (C7H10N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Nicotinamide impurity 19 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.
