Chemical Structure
Description
The molecular framework of 3,3-bis(1-cyclohexa-2,4-dienyl)-2-furanone 3,3-di(cyclohexa-2,4-dien-1-yl)furan-2-one 956-89-8 A845374 (C16H26O2) 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.
