Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2-Bis[bis(3,5-ditrifluoromethylphenyl)phosphino]ethane (CAS 199342-62-6), molecular formula C34H16F24P2 and molecular weight 942.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,2-Bis[bis(3,5-ditrifluoromethylphenyl)phosphino]ethane (C34H16F24P2) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 942.40 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.
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.
