Compared with other compounds in its class, the molecular weight of 343.37 g/mol gives Calcium Dobesilate Impurity N4 Bis-diethylamine Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Calcium Dobesilate Impurity N4 Bis-diethylamine Salt (CAS 57775-25-4, C6H6O8S2C4H11N) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
The molecular framework of Calcium Dobesilate Impurity N4 Bis-diethylamine Salt (C6H6O8S2C4H11N) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Calcium Dobesilate Impurity N4 Bis-diethylamine Salt 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.
