4-(3-(4-Aminophenyl)propanamido)-2-methylbenzene-1-sulfonyl fluoride (CAS 28321-29-1), molecular formula C16H17FN2O3S and molecular weight 336.38 g/mol, is a CATO reference standard with documented purity and traceability.
4-(3-(4-Aminophenyl)propanamido)-2-methylbenzene-1-sulfonyl fluoride (C16H17FN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
