Chemical Structure
Description
2-(3,4-Dichlorophenyl)-5-fluorobenzoic acid (CAS 926224-35-3) is a high-purity analytical reference standard with the molecular formula C13H7Cl2FO2 and a molecular weight of 285.10 g/mol.
2-(3,4-Dichlorophenyl)-5-fluorobenzoic acid (C13H7Cl2FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(3,4-Dichlorophenyl)-5-fluorobenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
