Chemical Structure

2,3,4,5-Tetraphenylfuran CAS 1056-77-5 chemical structure

Description

The occurrence of 2,3,4,5-Tetraphenylfuran is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,3,4,5-Tetraphenylfuran (CAS 1056-77-5), a certified reference material (molecular formula C28H20O, MW 372.46 g/mol) for analytical method development and quality control.

2,3,4,5-Tetraphenylfuran (C28H20O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
