Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(2-methyl-6-(methylthio)-9H-purin-9-yl)tetrahydrofuran-3,4-diol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.34 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).
CATO supplies (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(2-methyl-6-(methylthio)-9H-purin-9-yl)tetrahydrofuran-3,4-diol (CAS 172722-76-8), a certified reference material (molecular formula C12H16N4O4S, MW 312.34 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
