(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(6-(isopentylamino)-9H-purin-9-yl)tetrahydrofuran-3,4-diol CAS 17659-78-8 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,4R,5R)-2-(Hydroxymethyl)-5-(6-(isopentylamino)-9H-purin-9-yl)tetrahydrofuran-3,4-diol.

CATO supplies (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(6-(isopentylamino)-9H-purin-9-yl)tetrahydrofuran-3,4-diol (CAS 17659-78-8), a certified reference material (molecular formula C19H23N2O6P, MW 406.37 g/mol) for analytical method development and quality control.

(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(6-(isopentylamino)-9H-purin-9-yl)tetrahydrofuran-3,4-diol (C19H23N2O6P) 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.
