CATO supplies Amoxicillin Impurity 85(Mixture) (CAS CATO-C4X-114885), a pharmacopoeial impurity reference standard (molecular formula C8H14N2O4S, MW 234.27 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C8H14N2O4S, Amoxicillin Impurity 85(Mixture) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.27 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.
As a certified reference material (CRM), Amoxicillin Impurity 85(Mixture) 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.
