Description

3,3'''',6,6''''-Tetra-tert-butyl-6',6'''-bis(3,6-di-tert-butyl-9H-carbazol-9-yl)-9''-(4-(3,3'',6,6''-tetra-tert-butyl-9'H-[9,3':6',9''-tercarbazol]-9'-yl)phenyl)-9''H-9,3':9',3'':6'',9''':3''',9''''-quinquecarbazole (CAS 1025079-68-8), molecular formula C174H172N10 and molecular weight 2403.29 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,3'''',6,6''''-Tetra-tert-butyl-6',6'''-bis(3,6-di-tert-butyl-9H-carbazol-9-yl)-9''-(4-(3,3'',6,6''-tetra-tert-butyl-9'H-[9,3':6',9''-tercarbazol]-9'-yl)phenyl)-9''H-9,3':9',3'':6'',9''':3''',9''''-quinquecarbazole (C174H172N10) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 94.0, corresponding to approximately 94 ring(s) or double-bond equivalent(s). With a molecular weight of 2403.29 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.
