Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (((2R,3S,5R)-3-Hydroxy-5-(6-(methylamino)-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl)triphosphoric acid.
(((2R,3S,5R)-3-Hydroxy-5-(6-(methylamino)-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl)triphosphoric acid (CAS 5085-65-4) is a high-purity analytical reference standard with the molecular formula C11H18N5O12P3 and a molecular weight of 505.21 g/mol.
Structurally, (((2R,3S,5R)-3-Hydroxy-5-(6-(methylamino)-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl)triphosphoric acid (C11H18N5O12P3) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 505.21 g/mol, it falls into the moderately-high-molecular-weight range. 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.
