((2R,3S,4R,5R)-5-(6-Amino-2-(6-cyanohex-1-yn-1-yl)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate CAS 403731-19-1 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)-5-(6-Amino-2-(6-cyanohex-1-yn-1-yl)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate.

CATO supplies ((2R,3S,4R,5R)-5-(6-Amino-2-(6-cyanohex-1-yn-1-yl)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate (CAS 403731-19-1), a certified reference material (molecular formula C17H21N6O7P, MW 452.36 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, ((2R,3S,4R,5R)-5-(6-Amino-2-(6-cyanohex-1-yn-1-yl)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), ((2R,3S,4R,5R)-5-(6-Amino-2-(6-cyanohex-1-yn-1-yl)-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
