Chemical Structure
Description
The molecular framework of Ethyl (2Z)-2-[2-(4-bromophenyl)hydrazin-1-ylidene]-2-chloroacetate (C10H10BrClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/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 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).
Ethyl (2Z)-2-[2-(4-bromophenyl)hydrazin-1-ylidene]-2-chloroacetate (CAS 27143-10-8) is a high-purity analytical reference standard with the molecular formula C10H10BrClN2O2 and a molecular weight of 305.56 g/mol.
