Chemical Structure
Description
The occurrence of 1,2-Bis((2S,5S)-2,5-diethylphospholano)ethane(cyclooctadiene)rhodium(I) trifluoromethanesulfonate is closely related to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2-Bis((2S,5S)-2,5-diethylphospholano)ethane(cyclooctadiene)rhodium(I) trifluoromethanesulfonate (CAS 2709040-48-0), molecular formula C18H36P2RhCF3O3SC8H12 and molecular weight 674.59 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,2-Bis((2S,5S)-2,5-diethylphospholano)ethane(cyclooctadiene)rhodium(I) trifluoromethanesulfonate (C18H36P2RhCF3O3SC8H12) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 674.59 g/mol, it falls into the high-molecular-weight range. 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((2S,5S)-2,5-diethylphospholano)ethane(cyclooctadiene)rhodium(I) trifluoromethanesulfonate 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.
