Chemical Structure

2,2',4,4'-Tetraphenyl-[2,2'-bifuran]-5,5'(2H,2'H)-dione CAS 5369-54-0 chemical structure

Description

The occurrence of 2,2',4,4'-Tetraphenyl-[2,2'-bifuran]-5,5'(2H,2'H)-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2',4,4'-Tetraphenyl-[2,2'-bifuran]-5,5'(2H,2'H)-dione (CAS 5369-54-0), molecular formula C32H22O4 and molecular weight 470.51 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C32H22O4, 2,2',4,4'-Tetraphenyl-[2,2'-bifuran]-5,5'(2H,2'H)-dione contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 470.51 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.

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.
