Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
(1,5-Cyclooctadiene)bis(triphenylphosphine)rhodium(1+) tetrafluoroborate (CAS 32762-45-1) is a high-purity analytical reference standard with the molecular formula C44H42P2RhBF4 and a molecular weight of 822.48 g/mol.
The molecular framework of (1,5-Cyclooctadiene)bis(triphenylphosphine)rhodium(1+) tetrafluoroborate (C44H42P2RhBF4) is characterized by organophosphorus functionality, fluorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (1,5-Cyclooctadiene)bis(triphenylphosphine)rhodium(1+) tetrafluoroborate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
