Iodophenol Blue CAS 4430-24-4

Description

The occurrence of Iodophenol Blue is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Iodophenol Blue (CAS 4430-24-4) is a high-purity analytical reference standard with the molecular formula C19H10I4O5S and a molecular weight of 857.96 g/mol.

The molecular framework of Iodophenol Blue (C19H10I4O5S) is characterized by a flavonoid core, a sulfone group, 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. 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.
