Chemical Structure

Iopamidol EP Impurity F CAS 1869069-71-5 chemical structure

Description

The occurrence of Iopamidol EP Impurity F is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Iopamidol EP Impurity F (CAS 1869069-71-5), a pharmacopoeial impurity reference standard (molecular formula C16H20I3N3O6, MW 731.06 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C16H20I3N3O6, Iopamidol EP Impurity F contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 731.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
