(2R,3S,4S,5R)-2-(2,6-Diamino-9H-purin-9-yl)-4-fluoro-5-(hydroxymethyl)tetrahydrofuran-3-ol CAS 125391-75-5 chemical structure

Description

The molecular framework of (2R,3S,4S,5R)-2-(2,6-Diamino-9H-purin-9-yl)-4-fluoro-5-(hydroxymethyl)tetrahydrofuran-3-ol (C10H13FN6O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

(2R,3S,4S,5R)-2-(2,6-Diamino-9H-purin-9-yl)-4-fluoro-5-(hydroxymethyl)tetrahydrofuran-3-ol (CAS 125391-75-5) is a high-purity analytical reference standard with the molecular formula C10H13FN6O3 and a molecular weight of 284.25 g/mol.

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.
