Chemical Structure
Description
The molecular framework of 5,5'-((3,4-Dimethoxyphenyl)methylene)bis(2-methylfuran) (C19H20O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5,5'-((3,4-Dimethoxyphenyl)methylene)bis(2-methylfuran) (CAS 87125-64-2) is a high-purity analytical reference standard with the molecular formula C19H20O4 and a molecular weight of 312.36 g/mol.
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.
