Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (R)-3,3'-Bis(3,5-di-tert-butylphenyl)-[1,1'-binaphthalene]-2,2'-diol (CAS 756491-53-9), a certified reference material (molecular formula C48H54O2, MW 662.94 g/mol) for analytical method development and quality control.
The molecular framework of (R)-3,3'-Bis(3,5-di-tert-butylphenyl)-[1,1'-binaphthalene]-2,2'-diol (C48H54O2) is characterized by a carboxylic acid group, 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 manufactures (R)-3,3'-Bis(3,5-di-tert-butylphenyl)-[1,1'-binaphthalene]-2,2'-diol 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.
