Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 780.52 g/mol gives (2S,4S)-(-)-2,4-Bis(diphenylphosphino)pentane(norbornadiene)rhodium(I)hexafluorophosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2S,4S)-(-)-2,4-Bis(diphenylphosphino)pentane(norbornadiene)rhodium(I)hexafluorophosphate (CAS 154661-57-1), molecular formula C36H38P2RhF6P and molecular weight 780.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S,4S)-(-)-2,4-Bis(diphenylphosphino)pentane(norbornadiene)rhodium(I)hexafluorophosphate (C36H38P2RhF6P) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
