(2R,3R,5S)-2-(6-Amino-9H-purin-9-yl)-5-(((4-methoxyphenyl)diphenylmethoxy)methyl)tetrahydrofuran-3-ol (CAS 51763-58-7) is a high-purity analytical reference standard with the molecular formula C30H29N5O4 and a molecular weight of 523.58 g/mol.
The molecular framework of (2R,3R,5S)-2-(6-Amino-9H-purin-9-yl)-5-(((4-methoxyphenyl)diphenylmethoxy)methyl)tetrahydrofuran-3-ol (C30H29N5O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
