2,3,4,5-Tetrachloro-6-(2,4,5,7-tetraiodo-6-oxido-3-oxo-3H-xanthen-9-yl)benzoate (CAS 2438210-60-5), molecular formula C20H2Cl4I4O5 and molecular weight 971.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3,4,5-Tetrachloro-6-(2,4,5,7-tetraiodo-6-oxido-3-oxo-3H-xanthen-9-yl)benzoate (C20H2Cl4I4O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
