Chemical Structure

3,6-Bis(4-(tert-butyl)phenyl)-9H-carbazole CAS 728904-28-7 chemical structure

Description

CATO manufactures 3,6-Bis(4-(tert-butyl)phenyl)-9H-carbazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 3,6-Bis(4-(tert-butyl)phenyl)-9H-carbazole (CAS 728904-28-7), a certified reference material (molecular formula C32H33N, MW 431.61 g/mol) for analytical method development and quality control.

Structurally, 3,6-Bis(4-(tert-butyl)phenyl)-9H-carbazole (C32H33N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 431.61 g/mol, it falls into the moderately-high-molecular-weight range. 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.
