Chemical Structure
Description
The molecular framework of Dichloromethoxyoxobis(triphenylphosphine)rhenium (C37H33Cl2O2P2Re) is characterized by organophosphorus functionality, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Dichloromethoxyoxobis(triphenylphosphine)rhenium (CAS 83114-91-4), molecular formula C37H33Cl2O2P2Re and molecular weight 828.72 g/mol, is a CATO reference standard with documented purity and traceability.
