Chemical Structure
Description
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.
CATO supplies N-(9-((2R,3R,4S,5R)-5-(((tert-Butyldiphenylsilyl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)-9H-purin-6-yl)benzamide (CAS 77244-83-8), a certified reference material (molecular formula C33H35N5O5Si, MW 609.75 g/mol) for analytical method development and quality control.
N-(9-((2R,3R,4S,5R)-5-(((tert-Butyldiphenylsilyl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)-9H-purin-6-yl)benzamide (C33H35N5O5Si) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
