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.
((2R,3R,4S,5R)-3-(Benzoyloxy)-5-(2,6-dichloro-9H-purin-9-yl)-4-fluorotetrahydrofuran-2-yl)methyl benzoate (CAS 329187-80-6), molecular formula C24H17Cl2FN4O5 and molecular weight 531.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((2R,3R,4S,5R)-3-(Benzoyloxy)-5-(2,6-dichloro-9H-purin-9-yl)-4-fluorotetrahydrofuran-2-yl)methyl benzoate (C24H17Cl2FN4O5) is characterized by a flavonoid core, an amide 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
