Chemical Structure
Description
As a certified reference material (CRM), Ceftriaxone Impurity 46 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.
As a process- or degradation-related impurity, Ceftriaxone Impurity 46 (CAS CATO-C4X-116346, C12H13N5O5S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Based on its molecular formula C12H13N5O5S2, Ceftriaxone Impurity 46 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 371.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
