Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (Pentamethylcyclopentadienyl)rhodium(III) dichloride dimer (CAS 12354-85-7), a certified reference material (molecular formula Cl2RhC10H15, MW 309.04 g/mol) for analytical method development and quality control.
The molecular framework of (Pentamethylcyclopentadienyl)rhodium(III) dichloride dimer (Cl2RhC10H15) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
