Compared with other compounds in its class, the molecular weight of 367.36 g/mol gives (2R,3R,4S,5R)-2-(2-Hydrazinyl-6-(((R)-tetrahydrofuran-3-yl)amino)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2R,3R,4S,5R)-2-(2-Hydrazinyl-6-(((R)-tetrahydrofuran-3-yl)amino)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (CAS 920974-56-7), molecular formula C14H21N7O5 and molecular weight 367.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3R,4S,5R)-2-(2-Hydrazinyl-6-(((R)-tetrahydrofuran-3-yl)amino)-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (C14H21N7O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
