(1R)-3,3'-Bis(4-chlorophenyl)[1,1'-binaphthalene]-2,2'-diol (CAS 851615-05-9) is a high-purity analytical reference standard with the molecular formula C32H20Cl2O2 and a molecular weight of 507.41 g/mol.
The molecular framework of (1R)-3,3'-Bis(4-chlorophenyl)[1,1'-binaphthalene]-2,2'-diol (C32H20Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (1R)-3,3'-Bis(4-chlorophenyl)[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.
