Chemical Structure
Description
The occurrence of 2,4,5,7-TETRAIODO-6-HYDROXY-3-FLUORONE is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4,5,7-TETRAIODO-6-HYDROXY-3-FLUORONE (CAS 142189-38-6) is a high-purity analytical reference standard with the molecular formula C13H4I4O3 and a molecular weight of 715.79 g/mol.
Structurally, 2,4,5,7-TETRAIODO-6-HYDROXY-3-FLUORONE (C13H4I4O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 715.79 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
