Chemical Structure
Description
Structurally, 2-Amino-9-((2R,3R,4R,5R)-3-(((2S,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-3,9-dihydro-6H-purin-6-one (C15H21N5O9) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 415.36 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-Amino-9-((2R,3R,4R,5R)-3-(((2S,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-3,9-dihydro-6H-purin-6-one (CAS 148711-49-3), molecular formula C15H21N5O9 and molecular weight 415.36 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.
