Tolvaptan Impurity 61 CAS 2657689-34-2

Description

Tolvaptan Impurity 61 (CAS 2657689-34-2) is a certified pharmaceutical impurity reference standard with the molecular formula C42H36ClN3O5 and a molecular weight of 698.21 g/mol.

The molecular framework of Tolvaptan Impurity 61 (C42H36ClN3O5) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

CATO manufactures Tolvaptan Impurity 61 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.
