Description
CATO supplies Sivelestat Impurity 17 (CAS 10167-30-3), a pharmacopoeial impurity reference standard (molecular formula C11H13N3O4, MW 251.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C11H13N3O4, Sivelestat Impurity 17 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
