4-(4-Chlorophenyl)-9-phenyl-9H-carbazole CAS 1651187-59-5

Description

4-(4-Chlorophenyl)-9-phenyl-9H-carbazole (CAS 1651187-59-5) is a high-purity analytical reference standard with the molecular formula C24H16ClN and a molecular weight of 353.84 g/mol.

The molecular framework of 4-(4-Chlorophenyl)-9-phenyl-9H-carbazole (C24H16ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 4-(4-Chlorophenyl)-9-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.
