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 ((1R,2R,3S,4R)-4-(6-Amino-9H-purin-9-yl)-2,3-dihydroxycyclopentyl)methyl trihydrogen diphosphate.
CATO supplies ((1R,2R,3S,4R)-4-(6-Amino-9H-purin-9-yl)-2,3-dihydroxycyclopentyl)methyl trihydrogen diphosphate (CAS 42578-93-8), a certified reference material (molecular formula C11H17N5O9P2, MW 425.23 g/mol) for analytical method development and quality control.
((1R,2R,3S,4R)-4-(6-Amino-9H-purin-9-yl)-2,3-dihydroxycyclopentyl)methyl trihydrogen diphosphate (C11H17N5O9P2) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
