1,3,4,7-Tetraphenyl-5,6-di-p-tolylisobenzofuran CAS 62422-89-3

Description

The occurrence of 1,3,4,7-Tetraphenyl-5,6-di-p-tolylisobenzofuran is closely related to a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3,4,7-Tetraphenyl-5,6-di-p-tolylisobenzofuran (CAS 62422-89-3) is a high-purity analytical reference standard with the molecular formula C46H34O and a molecular weight of 602.76 g/mol.

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,3,4,7-Tetraphenyl-5,6-di-p-tolylisobenzofuran is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 602.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1,3,4,7-Tetraphenyl-5,6-di-p-tolylisobenzofuran meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
