Chemical Structure
Description
Based on its molecular formula C24H31N5O8S2, Amoxicillin EP Impurity O（Mixture）(Discontinued,See C4X-114824) contains a flavonoid core, 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 581.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a process- or degradation-related impurity, Amoxicillin EP Impurity O（Mixture）(Discontinued,See C4X-114824) (CAS CATO-C4X-114826, C24H31N5O8S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
