Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.34 g/mol gives N,N'-Di(o-tolyl)ethylenediamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N,N'-Di(o-tolyl)ethylenediamine (CAS 94-92-8), a certified reference material (molecular formula C16H20N2, MW 240.34 g/mol) for analytical method development and quality control.
The molecular framework of N,N'-Di(o-tolyl)ethylenediamine (C16H20N2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), N,N'-Di(o-tolyl)ethylenediamine 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.
