Chemical Structure
Description
(2R,3R,4S,5S)-2-(6-Amino-9H-purin-9-yl)-5-((sec-butylthio)methyl)tetrahydrofuran-3,4-diol (C14H21N5O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(2R,3R,4S,5S)-2-(6-Amino-9H-purin-9-yl)-5-((sec-butylthio)methyl)tetrahydrofuran-3,4-diol (CAS 61839-10-9), molecular formula C14H21N5O3S and molecular weight 339.41 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
