Chemical Structure

Cefotiam Impurity 22 CAS CATO-C4X-120422 chemical structure

Description

Owing to sulfur-containing functionality, Cefotiam Impurity 22 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.32 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.

Cefotiam Impurity 22 (CAS CATO-C4X-120422) is a certified pharmaceutical impurity reference standard with the molecular formula C6H14N2S2 and a molecular weight of 178.32 g/mol.

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), Cefotiam Impurity 22 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.
