Chemical Structure
Description
The molecular framework of 3-chloro-4,5-dimethoxyaniline hydrochloride (C8H10ClNO2HCl) 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).
CATO supplies 3-chloro-4,5-dimethoxyaniline hydrochloride (CAS 1909337-13-8), a certified reference material (molecular formula C8H10ClNO2HCl, MW 224.08 g/mol) for analytical method development and quality control.
