Chemical Structure

Cefathiamidine Impurity 4 CAS 1418224-75-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 351.17 g/mol gives Cefathiamidine Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cefathiamidine Impurity 4 (CAS 1418224-75-5), a pharmacopoeial impurity reference standard (molecular formula C10H11BrN2O5S, MW 351.17 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C10H11BrN2O5S, Cefathiamidine Impurity 4 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Cefathiamidine Impurity 4 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.
