N-(2-((4-chlorophenyl)sulfonyl)ethyl)-3-tosylpropanamide (C18H20ClNO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
N-(2-((4-chlorophenyl)sulfonyl)ethyl)-3-tosylpropanamide (CAS 337923-27-0) is a high-purity analytical reference standard with the molecular formula C18H20ClNO5S2 and a molecular weight of 429.94 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
