Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sultamicillin Tosilate Dihydrate EP Impurity G.
CATO supplies Sultamicillin Tosilate Dihydrate EP Impurity G (CAS CATO-C4X-188617), a pharmacopoeial impurity reference standard (molecular formula C50H60N8O18S4, MW 1189.31 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C50H60N8O18S4, Sultamicillin Tosilate Dihydrate EP Impurity G 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 1189.31 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.
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.
