CATO supplies (R)-4,12-Bis(4-methoxyphenyl)-[2.2]-paracyclophane(1,5-cyclooctadiene)rhodium(I) (tetrafluoroborate) (CAS 1038932-68-1), a certified reference material (molecular formula C52H54O4P2RhBF4, MW 994.66 g/mol) for analytical method development and quality control.
Structurally, (R)-4,12-Bis(4-methoxyphenyl)-[2.2]-paracyclophane(1,5-cyclooctadiene)rhodium(I) (tetrafluoroborate) (C52H54O4P2RhBF4) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 994.66 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.
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.
