Description
Carbocisteine Impurity 34 (CAS CATO-C4X-201034) is a certified pharmaceutical impurity reference standard with the molecular formula C7H9NO7S and a molecular weight of 251.21 g/mol.
Based on its molecular formula C7H9NO7S, Carbocisteine Impurity 34 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 251.21 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), Carbocisteine Impurity 34 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.
