Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.31 g/mol gives 3-(tert-Butyl)-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(tert-Butyl)-9H-carbazole (CAS 22401-74-7), molecular formula C16H17N and molecular weight 223.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(tert-Butyl)-9H-carbazole (C16H17N) 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).
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.
