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.
3-(3-(4-(2-Chloro-4-nitrophenoxy)butyl)ureido)benzene-1-sulfonyl fluoride (CAS 25313-31-9), molecular formula C17H17ClFN3O6S and molecular weight 445.85 g/mol, is a CATO reference standard with documented purity and traceability.
3-(3-(4-(2-Chloro-4-nitrophenoxy)butyl)ureido)benzene-1-sulfonyl fluoride (C17H17ClFN3O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
