3,9-Diethyl-5,11-bis(4-octylphenyl)-5,11-dihydroindolo[3,2-b]carbazole CAS 919513-72-7

Description

Compared with other compounds in its class, the molecular weight of 689.02 g/mol gives 3,9-Diethyl-5,11-bis(4-octylphenyl)-5,11-dihydroindolo[3,2-b]carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,9-Diethyl-5,11-bis(4-octylphenyl)-5,11-dihydroindolo[3,2-b]carbazole (CAS 919513-72-7), molecular formula C50H60N2 and molecular weight 689.02 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,9-Diethyl-5,11-bis(4-octylphenyl)-5,11-dihydroindolo[3,2-b]carbazole (C50H60N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
