<i>N</i>-Acetyl-<i>S</i>-(2-amino-9-(4-fluorobenzyl)-6-oxo-6,9-dihydro-1<i>H</i>-purin-8-yl)-L-cysteine (CAS 2241669-86-1), molecular formula C17H17FN6O4S and molecular weight 420.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, <i>N</i>-Acetyl-<i>S</i>-(2-amino-9-(4-fluorobenzyl)-6-oxo-6,9-dihydro-1<i>H</i>-purin-8-yl)-L-cysteine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
