Chemical Structure
Description
((2R,3R,4R,5R)-5-(6-Amino-9H-purin-9-yl)-4-fluoro-3-hydroxytetrahydrofuran-2-yl)methyl trihydrogen diphosphate (C10H14FN5O9P2) contains a carbohydrate-derived structure, an amide group, a phosphate ester group, fluorine substitution. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
((2R,3R,4R,5R)-5-(6-Amino-9H-purin-9-yl)-4-fluoro-3-hydroxytetrahydrofuran-2-yl)methyl trihydrogen diphosphate (CAS 68357-16-4) is a high-purity analytical reference standard with the molecular formula C10H14FN5O9P2 and a molecular weight of 429.19 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.
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.
