Ethyl 5-cyclopropyl-2-(4-fluorophenyl)-6-(N-(methylsulfonyl)methylsulfonamido)benzofuran-3-carboxylate (CAS 1185313-40-9), molecular formula C22H22FNO7S2 and molecular weight 495.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 5-cyclopropyl-2-(4-fluorophenyl)-6-(N-(methylsulfonyl)methylsulfonamido)benzofuran-3-carboxylate (C22H22FNO7S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
