3-(2,4-Dichlorophenoxy)-6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophene 1-oxide CAS 477762-76-8

Description

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.

3-(2,4-Dichlorophenoxy)-6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophene 1-oxide (CAS 477762-76-8), molecular formula C22H16Cl2O4S and molecular weight 447.33 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C22H16Cl2O4S, 3-(2,4-Dichlorophenoxy)-6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophene 1-oxide contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 447.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
