Chemical Structure
Description
The occurrence of 8,8-Dimethyl-5,8-dihydroindeno[2,1-c]carbazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 8,8-Dimethyl-5,8-dihydroindeno[2,1-c]carbazole (CAS 1623813-70-6), a certified reference material (molecular formula C21H17N, MW 283.37 g/mol) for analytical method development and quality control.
The molecular framework of 8,8-Dimethyl-5,8-dihydroindeno[2,1-c]carbazole (C21H17N) 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.
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.
As a certified reference material (CRM), 8,8-Dimethyl-5,8-dihydroindeno[2,1-c]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.
