Chemical Structure

3,4-Dimethyl-2,5-diphenylfuran CAS 51181-43-2 chemical structure

Description

Based on its molecular formula C18H16O, 3,4-Dimethyl-2,5-diphenylfuran contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 3,4-Dimethyl-2,5-diphenylfuran (CAS 51181-43-2), a certified reference material (molecular formula C18H16O, MW 248.32 g/mol) for analytical method development and quality control.

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.
