Chemical Structure
Description
2-amino-9-[(2R,3R,4S,5R)-3,4-dihydroxy-5-[[hydroxy-[hydroxy(phosphonooxy)phosphoryl]oxy-phosphoryl]oxymethyl]tetrahydrofuran-2-yl]-7-methyl-purin-7-ium-6-olate (CAS 26554-26-7) is a high-purity analytical reference standard with the molecular formula C11H25N5O14P3 and a molecular weight of 544.26 g/mol.
The molecular framework of 2-amino-9-[(2R,3R,4S,5R)-3,4-dihydroxy-5-[[hydroxy-[hydroxy(phosphonooxy)phosphoryl]oxy-phosphoryl]oxymethyl]tetrahydrofuran-2-yl]-7-methyl-purin-7-ium-6-olate (C11H25N5O14P3) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
