Compared with other compounds in its class, the molecular weight of 524.65 g/mol gives 9,9'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(9H-carbazole) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9,9'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(9H-carbazole) (CAS 226958-06-1), molecular formula C39H28N2 and molecular weight 524.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 9,9'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(9H-carbazole) (C39H28N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 524.65 g/mol, it falls into the moderately-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.
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.
