Chemical Structure
Description
The molecular framework of 2-(Dimethylphosphinyl)-3-methoxybenzenamine (C9H14NO2P) is characterized by an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
