Chemical Structure

(2S,3S,4R,5R)-2-(7-Acetamido-1H-pyrazolo[4,3-d]pyrimidin-3-yl)-5-(acetoxymethyl)tetrahydrofuran-3,4-diyl diacetate CAS 13351-66-1 chemical structure

Description

The occurrence of (2S,3S,4R,5R)-2-(7-Acetamido-1H-pyrazolo[4,3-d]pyrimidin-3-yl)-5-(acetoxymethyl)tetrahydrofuran-3,4-diyl diacetate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2S,3S,4R,5R)-2-(7-Acetamido-1H-pyrazolo[4,3-d]pyrimidin-3-yl)-5-(acetoxymethyl)tetrahydrofuran-3,4-diyl diacetate (CAS 13351-66-1), a certified reference material (molecular formula C18H21N5O8, MW 435.39 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2S,3S,4R,5R)-2-(7-Acetamido-1H-pyrazolo[4,3-d]pyrimidin-3-yl)-5-(acetoxymethyl)tetrahydrofuran-3,4-diyl diacetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 435.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
