Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rhodium(I)-cis,cis-1,5-cyclooctadiene-1,10-phenanthroline (chloride).
Rhodium(I)-cis,cis-1,5-cyclooctadiene-1,10-phenanthroline (chloride) (CAS 54324-73-1), molecular formula C20H20N2RhCl and molecular weight 426.75 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Rhodium(I)-cis,cis-1,5-cyclooctadiene-1,10-phenanthroline (chloride) (C20H20N2RhCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 426.75 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
