Chemical Structure
Description
(2R,3R,4S,5R)-2-(6-((4-Chlorobenzyl)thio)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (C17H17ClN4O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(2R,3R,4S,5R)-2-(6-((4-Chlorobenzyl)thio)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (CAS 51375-21-4) is a high-purity analytical reference standard with the molecular formula C17H17ClN4O4S and a molecular weight of 408.86 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
