Chemical Structure
Description
The occurrence of Dexrazoxane Impurity 1 2H2SO4 is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dexrazoxane Impurity 1 2H2SO4 (CAS CATO-C4X-20201) is a certified pharmaceutical impurity reference standard with the molecular formula C11H18N4O5H2O4S and a molecular weight of 384.36 g/mol.
Based on its molecular formula C11H18N4O5H2O4S, Dexrazoxane Impurity 1 2H2SO4 contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 384.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Dexrazoxane Impurity 1 2H2SO4 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.
