Chemical Structure
Description
The molecular framework of Candesartan Cilexetil EP Impurity H (C52H48N6O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a process- or degradation-related impurity, Candesartan Cilexetil EP Impurity H (CAS 170791-09-0, C52H48N6O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
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.
CATO manufactures Candesartan Cilexetil EP Impurity H under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
