Description
N-(9-((2R,4S,5R)-4-Hydroxy-5-((trityloxy)methyl)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-3H-purin-2-yl)isobutyramide (CAS 75759-63-6), molecular formula C33H33N5O5 and molecular weight 579.65 g/mol, is a CATO reference standard with documented purity and traceability.
N-(9-((2R,4S,5R)-4-Hydroxy-5-((trityloxy)methyl)tetrahydrofuran-2-yl)-6-oxo-6,9-dihydro-3H-purin-2-yl)isobutyramide (C33H33N5O5) 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. 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.
