Description

Compared with other compounds in its class, the molecular weight of 676.84 g/mol gives 9,9'-(9,9-Di-p-tolyl-9H-fluorene-2,7-diyl)bis(9H-carbazole) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 9,9'-(9,9-Di-p-tolyl-9H-fluorene-2,7-diyl)bis(9H-carbazole) (CAS 1174006-50-8), a certified reference material (molecular formula C51H36N2, MW 676.84 g/mol) for analytical method development and quality control.

Structurally, 9,9'-(9,9-Di-p-tolyl-9H-fluorene-2,7-diyl)bis(9H-carbazole) (C51H36N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 35.0, corresponding to approximately 35 ring(s) or double-bond equivalent(s). With a molecular weight of 676.84 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
