Description

The occurrence of ((2R,3S,4R,5R)-5-(6-((2-((6-Aminohexyl)amino)-2-oxoethyl)amino)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate is closely related to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

((2R,3S,4R,5R)-5-(6-((2-((6-Aminohexyl)amino)-2-oxoethyl)amino)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 81287-63-0), molecular formula C18H30N7O8P and molecular weight 503.45 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, ((2R,3S,4R,5R)-5-(6-((2-((6-Aminohexyl)amino)-2-oxoethyl)amino)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 503.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
