Chemical Structure
Description
The molecular framework of 2-(2,4-Dichloro-3-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H17BCl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
