CATO supplies 4-(2-(2-Chloro-4-nitrophenoxy)acetamido)-2-methylbenzene-1-sulfonyl fluoride (CAS 25292-73-3), a certified reference material (molecular formula C15H12ClFN2O6S, MW 402.78 g/mol) for analytical method development and quality control.
The molecular framework of 4-(2-(2-Chloro-4-nitrophenoxy)acetamido)-2-methylbenzene-1-sulfonyl fluoride (C15H12ClFN2O6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
