Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rhodium(1+), [(1,2,5,6-η)-1,5-cyclooctadiene][(2R,2′R,5R,5′R)-1,1′-(1,2-ethanediyl)bis[2,5-bis(1-methylethyl)phospholane-κP]]-, tetrafluoroborate(1-).
Rhodium(1+), [(1,2,5,6-η)-1,5-cyclooctadiene][(2R,2′R,5R,5′R)-1,1′-(1,2-ethanediyl)bis[2,5-bis(1-methylethyl)phospholane-κP]]-, tetrafluoroborate(1-) (CAS 895541-38-5), molecular formula C22H43P2RhC8H12BF4 and molecular weight 667.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Rhodium(1+), [(1,2,5,6-η)-1,5-cyclooctadiene][(2R,2′R,5R,5′R)-1,1′-(1,2-ethanediyl)bis[2,5-bis(1-methylethyl)phospholane-κP]]-, tetrafluoroborate(1-) (C22H43P2RhC8H12BF4) contains organophosphorus functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 667.43 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.
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.
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.
