Chemical Structure

9-Ethyl-9H-carbazole-2-carbaldehyde CAS 56166-62-2 chemical structure

Description

CATO supplies 9-Ethyl-9H-carbazole-2-carbaldehyde (CAS 56166-62-2), a certified reference material (molecular formula C15H13NO, MW 223.27 g/mol) for analytical method development and quality control.

The molecular framework of 9-Ethyl-9H-carbazole-2-carbaldehyde (C15H13NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
