Chemical Structure
Description
The molecular framework of 2-Chlorphenylphosphonsaeurediethylester 28036-18-2 (C10H14ClO3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
