Chemical Structure
Description
The molecular framework of 5,11-Dihydroindolo[3,2-b]carbazole-6-carbonitrile (C19H11N3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5,11-Dihydroindolo[3,2-b]carbazole-6-carbonitrile (CAS 1956321-98-4) is a high-purity analytical reference standard with the molecular formula C19H11N3 and a molecular weight of 281.31 g/mol.
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 5,11-Dihydroindolo[3,2-b]carbazole-6-carbonitrile 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.
