Docetaxel Impurity 57 CAS CATO-C4X-161957

Description

Compared with other compounds in its class, the molecular weight of 1101.41 g/mol gives Docetaxel Impurity 57 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Docetaxel Impurity 57 (CAS CATO-C4X-161957), a pharmacopoeial impurity reference standard (molecular formula C54H60Cl3NO17, MW 1101.41 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Docetaxel Impurity 57 (C54H60Cl3NO17) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Docetaxel Impurity 57 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.
