The occurrence of 2-(4-(2-Butylbenzofuran-3-carbonyl)-2,6-diiodophenoxy)acetic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-(2-Butylbenzofuran-3-carbonyl)-2,6-diiodophenoxy)acetic acid (CAS 147030-47-5), molecular formula C21H18I2O5 and molecular weight 604.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-(2-Butylbenzofuran-3-carbonyl)-2,6-diiodophenoxy)acetic acid (C21H18I2O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, 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.
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.
