Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.12 g/mol gives Mesna Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Mesna Impurity 7 (CAS CATO-C4X-16927) is a certified pharmaceutical impurity reference standard with the molecular formula C3H7BrO3S2 and a molecular weight of 235.12 g/mol.
The molecular framework of Mesna Impurity 7 (C3H7BrO3S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Mesna Impurity 7 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.
