The occurrence of (4aR,6R,7R,7aR)-6-(6-Butyramido-9H-purin-9-yl)-2-hydroxy-2-oxidotetrahydro-4H-furo[3,2-d][1,3,2]dioxaphosphinin-7-yl butyrate 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.
(4aR,6R,7R,7aR)-6-(6-Butyramido-9H-purin-9-yl)-2-hydroxy-2-oxidotetrahydro-4H-furo[3,2-d][1,3,2]dioxaphosphinin-7-yl butyrate (CAS 362-74-3) is a high-purity analytical reference standard with the molecular formula C18H24N5O8P and a molecular weight of 469.39 g/mol.
(4aR,6R,7R,7aR)-6-(6-Butyramido-9H-purin-9-yl)-2-hydroxy-2-oxidotetrahydro-4H-furo[3,2-d][1,3,2]dioxaphosphinin-7-yl butyrate (C18H24N5O8P) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. 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.
