Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.34 g/mol gives 1,4,5,8,9-Pentamethyl-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,4,5,8,9-Pentamethyl-9H-carbazole (CAS 27477-88-9), a certified reference material (molecular formula C17H19N, MW 237.34 g/mol) for analytical method development and quality control.
The molecular framework of 1,4,5,8,9-Pentamethyl-9H-carbazole (C17H19N) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,4,5,8,9-Pentamethyl-9H-carbazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
