Chemical Structure
Description
((2R,3R,4R,5R)-5-(2-Amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-3-hydroxy-4-methoxytetrahydrofuran-2-yl)methyl tetrahydrogen triphosphate (CAS 61556-44-3), molecular formula C11H18N5O14P3 and molecular weight 537.21 g/mol, is a CATO reference standard with documented purity and traceability.
((2R,3R,4R,5R)-5-(2-Amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-3-hydroxy-4-methoxytetrahydrofuran-2-yl)methyl tetrahydrogen triphosphate (C11H18N5O14P3) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. It is notably hygroscopic, 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).
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.
