Description
As a certified reference material (CRM), Enalapril EP Impurity H Hydrochloride(Mixture of Diastereomers) 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.
Enalapril EP Impurity H Hydrochloride(Mixture of Diastereomers) (CAS CATO-C4X-13349) is a certified pharmaceutical impurity reference standard with the molecular formula C20H34N2O5HCl and a molecular weight of 418.96 g/mol.
The molecular framework of Enalapril EP Impurity H Hydrochloride(Mixture of Diastereomers) (C20H34N2O5HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
