Chemical Structure
Description
The occurrence of (E)-3-(2-Chlorophenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-3-(2-Chlorophenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one (CAS 204974-26-5) is a high-purity analytical reference standard with the molecular formula C15H11ClO2 and a molecular weight of 258.70 g/mol.
The molecular framework of (E)-3-(2-Chlorophenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one (C15H11ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
