Chemical Structure

2-(3,4-Dichlorophenyl)-N-methylacetamide CAS 16505-75-2 chemical structure

Description

The occurrence of 2-(3,4-Dichlorophenyl)-N-methylacetamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3,4-Dichlorophenyl)-N-methylacetamide (CAS 16505-75-2) is a high-purity analytical reference standard with the molecular formula C9H9Cl2NO and a molecular weight of 218.08 g/mol.

The molecular framework of 2-(3,4-Dichlorophenyl)-N-methylacetamide (C9H9Cl2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
