Chemical Structure
Description
CATO supplies Kitasamycin impurity 1 (CAS CATO-C4X-33801), a pharmacopoeial impurity reference standard (molecular formula C41H69NO15, MW 815.98 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Kitasamycin impurity 1 (C41H69NO15) 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.
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), Kitasamycin impurity 1 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.
