Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 777.09 g/mol gives (R)-Iopamidol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-Iopamidol (CAS 88375-91-1) is a high-purity analytical reference standard with the molecular formula C17H22I3N3O8 and a molecular weight of 777.09 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, (R)-Iopamidol is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 777.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
