Chemical Structure

(1S,2S)-1,2-di-p-tolylethane-1,2-diamine CAS 162490-70-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (1S,2S)-1,2-di-p-tolylethane-1,2-diamine (CAS 162490-70-2), a certified reference material (molecular formula C16H20N2, MW 240.34 g/mol) for analytical method development and quality control.

The molecular framework of (1S,2S)-1,2-di-p-tolylethane-1,2-diamine (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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), (1S,2S)-1,2-di-p-tolylethane-1,2-diamine 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.
