(E)-9-ethyl-3-((2-ethyl-2-(m-tolyl)hydrazono)methyl)-9H-carbazole CAS 81380-24-7

Description

Compared with other compounds in its class, the molecular weight of 355.48 g/mol gives (E)-9-ethyl-3-((2-ethyl-2-(m-tolyl)hydrazono)methyl)-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (E)-9-ethyl-3-((2-ethyl-2-(m-tolyl)hydrazono)methyl)-9H-carbazole (CAS 81380-24-7), a certified reference material (molecular formula C24H25N3, MW 355.48 g/mol) for analytical method development and quality control.

Structurally, (E)-9-ethyl-3-((2-ethyl-2-(m-tolyl)hydrazono)methyl)-9H-carbazole (C24H25N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 355.48 g/mol, it falls into the moderately-high-molecular-weight range. 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.

As a certified reference material (CRM), (E)-9-ethyl-3-((2-ethyl-2-(m-tolyl)hydrazono)methyl)-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.
