Chemical Structure
Description
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.
CATO supplies Prucalopride Impurity 36 (CAS 232941-14-9), a pharmacopoeial impurity reference standard (molecular formula C10H9BrClNO4, MW 322.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C10H9BrClNO4, Prucalopride Impurity 36 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.54 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.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
