Chemical Structure
Description
CATO supplies 3-(Ethoxycarbonyl)-1-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)-pyridinium Triflate (CAS 936945-09-4), a certified reference material (molecular formula C19H24NO9, MW 410.40 g/mol) for analytical method development and quality control.
Structurally, 3-(Ethoxycarbonyl)-1-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)-pyridinium Triflate (C19H24NO9) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 410.40 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).
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.
