Chemical Structure
Description
The occurrence of 1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene(cyclooctadiene)rhodium(I) tetrafluoroborate is closely related to organophosphorus functionality, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene(cyclooctadiene)rhodium(I) tetrafluoroborate (CAS 210057-23-1) is a high-purity analytical reference standard with the molecular formula C18H28P2RhC8H12BF3F and a molecular weight of 604.27 g/mol.
Owing to organophosphorus functionality, fluorine substitution, an aromatic ring system, 1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene(cyclooctadiene)rhodium(I) tetrafluoroborate is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 604.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene(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.
