Chemical Structure

rel-(1R,2S,3R,5R)-3-(5-Amino-7-(methylthio)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)-5-(hydroxymethyl)cyclopentane-1,2-diol CAS 88801-90-5 chemical structure

Description

rel-(1R,2S,3R,5R)-3-(5-Amino-7-(methylthio)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)-5-(hydroxymethyl)cyclopentane-1,2-diol (CAS 88801-90-5) is a high-purity analytical reference standard with the molecular formula C11H16N6O3S and a molecular weight of 312.35 g/mol.

Structurally, rel-(1R,2S,3R,5R)-3-(5-Amino-7-(methylthio)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)-5-(hydroxymethyl)cyclopentane-1,2-diol (C11H16N6O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 312.35 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
