Chemical Structure
Description
The molecular framework of 4-(P-tolyl)-5,6-dihydro-4H-pyrido[3,2,1-jk]carbazole (C22H19N) 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).
CATO supplies 4-(P-tolyl)-5,6-dihydro-4H-pyrido[3,2,1-jk]carbazole (CAS 198019-25-9), a certified reference material (molecular formula C22H19N, MW 297.39 g/mol) for analytical method development and quality control.
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-(P-tolyl)-5,6-dihydro-4H-pyrido[3,2,1-jk]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.
