Chemical Structure

2,7-Di(pyridin-4-yl)-9H-carbazole CAS 2768518-72-3 chemical structure

Description

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.

2,7-Di(pyridin-4-yl)-9H-carbazole (CAS 2768518-72-3) is a high-purity analytical reference standard with the molecular formula C22H15N3 and a molecular weight of 321.37 g/mol.

The molecular framework of 2,7-Di(pyridin-4-yl)-9H-carbazole (C22H15N3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
