Chemical Structure
Description
N-(2-hydroxyethyl)-2,4,6-triiodo-3-(N-methylacetamido)-5-((2S,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanamido)benzamide (CAS 56562-79-9) is a high-purity analytical reference standard with the molecular formula C18H24I3N3O9 and a molecular weight of 807.11 g/mol.
The molecular framework of N-(2-hydroxyethyl)-2,4,6-triiodo-3-(N-methylacetamido)-5-((2S,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanamido)benzamide (C18H24I3N3O9) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
