Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 299.30 g/mol gives Topiramate EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Topiramate EP Impurity C (CAS 106881-41-8) is a certified pharmaceutical impurity reference standard with the molecular formula C9H17NO8S and a molecular weight of 299.30 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Topiramate EP Impurity C is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Topiramate EP Impurity C 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.
