Vinorelbine EP Impurity D CAS CATO-C4X-26425

Description

The occurrence of Vinorelbine EP Impurity D is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Vinorelbine EP Impurity D (CAS CATO-C4X-26425) is a certified pharmaceutical impurity reference standard with the molecular formula C45H54N4O9 and a molecular weight of 794.93 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Vinorelbine EP Impurity D is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 794.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Vinorelbine EP Impurity D 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.
