(4'-Bromo-[1,1'-biphenyl]-4-yl)(hydroxy)-lambda3-iodanyl 4-methylbenzenesulfonate CAS 919474-55-8

Description

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.

(4'-Bromo-[1,1'-biphenyl]-4-yl)(hydroxy)-lambda3-iodanyl 4-methylbenzenesulfonate (CAS 919474-55-8) is a high-purity analytical reference standard with the molecular formula C19H16BrIO4S and a molecular weight of 547.20 g/mol.

The molecular framework of (4'-Bromo-[1,1'-biphenyl]-4-yl)(hydroxy)-lambda3-iodanyl 4-methylbenzenesulfonate (C19H16BrIO4S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
