(3R,4S)-1-((4-Amino-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methyl)-4-((methylthio)methyl)pyrrolidin-3-ol (CAS 653592-04-2) is a high-purity analytical reference standard with the molecular formula C13H19N5OS and a molecular weight of 293.39 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, (3R,4S)-1-((4-Amino-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methyl)-4-((methylthio)methyl)pyrrolidin-3-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.39 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.
