1,2-Dibromo-1,2-bis(3,4-dimethoxyphenyl)ethane CAS 320576-20-3

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.

CATO supplies 1,2-Dibromo-1,2-bis(3,4-dimethoxyphenyl)ethane (CAS 320576-20-3), a certified reference material (molecular formula C18H20Br2O4, MW 460.16 g/mol) for analytical method development and quality control.

The molecular framework of 1,2-Dibromo-1,2-bis(3,4-dimethoxyphenyl)ethane (C18H20Br2O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine 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.

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.
