Chemical Structure
Description
(1R)-2'-(Diphenylphosphino)-1,1'-binaphthalenyl-2-ol (CAS 149917-88-4), molecular formula C32H23OP and molecular weight 454.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1R)-2'-(Diphenylphosphino)-1,1'-binaphthalenyl-2-ol (C32H23OP) is characterized by organophosphorus functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (1R)-2'-(Diphenylphosphino)-1,1'-binaphthalenyl-2-ol 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.
