Chemical Structure
Description
The occurrence of (3R,4R)-(+)-Bis(diphenylphosphino)-1-benzylpyrrolidine(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (3R,4R)-(+)-Bis(diphenylphosphino)-1-benzylpyrrolidine(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate (CAS 99143-48-3), a certified reference material (molecular formula C43H45NP2RhBF4, MW 827.50 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, fluorine substitution, (3R,4R)-(+)-Bis(diphenylphosphino)-1-benzylpyrrolidine(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 827.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), (3R,4R)-(+)-Bis(diphenylphosphino)-1-benzylpyrrolidine(1,5-cyclooctadiene)rhodium(I) 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.
