Chemical Structure
Description
The molecular framework of 2,5-Dichloro-4-(5,5-dimethyl-1,3-dioxan-2-yl)butyrophenone (C16H20Cl2O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2,5-Dichloro-4-(5,5-dimethyl-1,3-dioxan-2-yl)butyrophenone (CAS 898756-93-9), molecular formula C16H20Cl2O3 and molecular weight 331.23 g/mol, is a CATO reference standard with documented purity and traceability.
