Chemical Structure
Description
The occurrence of 2-(2,3-Dichlorophenyl)butanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2,3-Dichlorophenyl)butanoic acid (CAS 1248428-33-2), molecular formula C10H10Cl2O2 and molecular weight 233.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2,3-Dichlorophenyl)butanoic acid (C10H10Cl2O2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
