TFB 220797-16-0 Poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(4,4'-(N -(4-sec-butylphenyl)-diphenylamine)] (CAS 220797-16-0), molecular formula C53H67N and molecular weight 718.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, TFB 220797-16-0 Poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(4,4'-(N -(4-sec-butylphenyl)-diphenylamine)] (C53H67N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 718.11 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.
