Chemical Structure
Description
As a certified reference material (CRM), (1<I>S</I>, 2<I>S</I>)-1,2-bis(4-nitrophenyl)ethylenediamine dihydrochloride 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.
(1<I>S</I>, 2<I>S</I>)-1,2-bis(4-nitrophenyl)ethylenediamine dihydrochloride (CAS 1052707-07-9), molecular formula C14H26N4O4HCl and molecular weight 350.84 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1<I>S</I>, 2<I>S</I>)-1,2-bis(4-nitrophenyl)ethylenediamine dihydrochloride (C14H26N4O4HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
