Chemical Structure
Description
The molecular framework of (1S,2S)-1,2-bis(4-bromophenyl)ethane-1,2-diamine (C14H14Br2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(1S,2S)-1,2-bis(4-bromophenyl)ethane-1,2-diamine (CAS 821766-66-9), molecular formula C14H14Br2N2 and molecular weight 370.08 g/mol, is a CATO reference standard with documented purity and traceability.
