Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 420.46 g/mol gives 4,4'-(2,2-Diphenylethene-1,1-diyl)dibenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,4'-(2,2-Diphenylethene-1,1-diyl)dibenzoic acid (CAS 1609575-40-7), a certified reference material (molecular formula C28H20O4, MW 420.46 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(2,2-Diphenylethene-1,1-diyl)dibenzoic acid (C28H20O4) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,4'-(2,2-Diphenylethene-1,1-diyl)dibenzoic acid 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.
