Chemical Structure
Description
The occurrence of 5-Chloro-3-(3,4-dichlorophenyl)benzoic 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.
5-Chloro-3-(3,4-dichlorophenyl)benzoic acid (CAS 1261984-79-5) is a high-purity analytical reference standard with the molecular formula C13H7Cl3O2 and a molecular weight of 301.55 g/mol.
5-Chloro-3-(3,4-dichlorophenyl)benzoic acid (C13H7Cl3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
