N-(thiophen-2-ylmethyl)-2-(2-((1-tosyl-1H-indol-4-yl)oxy)ethoxy)ethan-1-amine (CAS 439094-58-3), molecular formula C24H26N2O4S2 and molecular weight 470.60 g/mol, is a CATO reference standard with documented purity and traceability.
N-(thiophen-2-ylmethyl)-2-(2-((1-tosyl-1H-indol-4-yl)oxy)ethoxy)ethan-1-amine (C24H26N2O4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
