Chemical Structure
Description
The occurrence of 3,5-dimethoxy-2-methylaniline hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-dimethoxy-2-methylaniline hydrochloride (CAS 33580-40-4) is a high-purity analytical reference standard with the molecular formula C9H13NO2HCl and a molecular weight of 203.67 g/mol.
The molecular framework of 3,5-dimethoxy-2-methylaniline hydrochloride (C9H13NO2HCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
