Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 551.52 g/mol gives Carbocisteine Impurity 58 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carbocisteine Impurity 58 (CAS CATO-C4X-201058) is a certified pharmaceutical impurity reference standard with the molecular formula C21H29NO14S and a molecular weight of 551.52 g/mol.
The molecular framework of Carbocisteine Impurity 58 (C21H29NO14S) is characterized by a flavonoid core, an amide group, a sulfone 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. 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), Carbocisteine Impurity 58 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.
