Naltrexone EP Impurity E CAS 767615-69-0 chemical structure

Description

Naltrexone EP Impurity E (CAS 767615-69-0) is a certified pharmaceutical impurity reference standard with the molecular formula C24H29NO4 and a molecular weight of 395.49 g/mol.

Naltrexone EP Impurity E (C24H29NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Naltrexone EP Impurity E 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.
