6-Amino-2-(2-deoxy-β-D-ribofuranosyl)-2,5-dihydro-4H-pyrazolo-[3,4-d]-pyrimidin-4-one CAS 109737-94-2 chemical structure

Description

The occurrence of 6-Amino-2-(2-deoxy-β-D-ribofuranosyl)-2,5-dihydro-4H-pyrazolo-[3,4-d]-pyrimidin-4-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-Amino-2-(2-deoxy-β-D-ribofuranosyl)-2,5-dihydro-4H-pyrazolo-[3,4-d]-pyrimidin-4-one (CAS 109737-94-2), a certified reference material (molecular formula C10H13N5O4, MW 267.24 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6-Amino-2-(2-deoxy-β-D-ribofuranosyl)-2,5-dihydro-4H-pyrazolo-[3,4-d]-pyrimidin-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
