Chemical Structure
Description
The molecular framework of Busulfan Impurity 2 (C10H22O9S3) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
Busulfan Impurity 2 (CAS CATO-C4X-14552) is a certified pharmaceutical impurity reference standard with the molecular formula C10H22O9S3 and a molecular weight of 382.47 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.
As a certified reference material (CRM), Busulfan Impurity 2 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.
