(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(2-methoxy-9H-purin-9-yl)tetrahydrofuran-3,4-diol CAS 39638-84-1

Description

(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(2-methoxy-9H-purin-9-yl)tetrahydrofuran-3,4-diol (C2H4Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(2-methoxy-9H-purin-9-yl)tetrahydrofuran-3,4-diol (CAS 39638-84-1), molecular formula C2H4Cl2O2S and molecular weight 163.02 g/mol, is a CATO reference standard with documented purity and traceability.

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.
