Chemical Structure
Description
The molecular framework of 3-(4-Hydroxy-3-methoxybenzylidene)pentane-2,4-dione (C13H14O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
CATO supplies 3-(4-Hydroxy-3-methoxybenzylidene)pentane-2,4-dione (CAS 91418-45-0), a certified reference material (molecular formula C13H14O4, MW 234.25 g/mol) for analytical method development and quality control.
