Chemical Structure

1-(4-Chloro-2,6-dimethylpyridin-3-yl)ethan-1-one CAS 79039-89-7 chemical structure

Description

The molecular framework of 1-(4-Chloro-2,6-dimethylpyridin-3-yl)ethan-1-one (C9H10ClNO) 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.
