CATO supplies (2R,3R,4S,5R)-2-(6-(Cyclopentylamino)-8-(propylamino)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (CAS 174365-18-5), a certified reference material (molecular formula C18H28N6O4, MW 392.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H28N6O4, (2R,3R,4S,5R)-2-(6-(Cyclopentylamino)-8-(propylamino)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 392.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
