The molecular framework of 4,7-Diphenyl-1,3-di-p-tolylisobenzofuran (C34H26O) is characterized by a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
CATO supplies 4,7-Diphenyl-1,3-di-p-tolylisobenzofuran (CAS 62422-91-7), a certified reference material (molecular formula C34H26O, MW 450.57 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.
CATO manufactures 4,7-Diphenyl-1,3-di-p-tolylisobenzofuran under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
