Chemical Structure
Description
The occurrence of 2,3-Bis[(2S,5S)-2,5-dimethylphospholanyl]maleic anhydride(1,5-cyclooctadiene)rhodium (I) tetrafluoroborate is closely related to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3-Bis[(2S,5S)-2,5-dimethylphospholanyl]maleic anhydride(1,5-cyclooctadiene)rhodium (I) tetrafluoroborate (CAS 821793-39-9), a certified reference material (molecular formula C24H36O3P2RhBF4, MW 624.21 g/mol) for analytical method development and quality control.
Structurally, 2,3-Bis[(2S,5S)-2,5-dimethylphospholanyl]maleic anhydride(1,5-cyclooctadiene)rhodium (I) tetrafluoroborate (C24H36O3P2RhBF4) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 624.21 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
