Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Vincristine EP Impurity B is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 808.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Vincristine EP Impurity B (CAS CATO-C4X-208912) is a certified pharmaceutical impurity reference standard with the molecular formula C46H56N4O9 and a molecular weight of 808.96 g/mol.
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 Vincristine EP Impurity B 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.
