Chemical Structure
Description
3-(2,4-Dimethoxyphenyl)-5-fluorobenzoic acid (CAS 1261895-15-1) is a high-purity analytical reference standard with the molecular formula C15H13FO4 and a molecular weight of 276.26 g/mol.
3-(2,4-Dimethoxyphenyl)-5-fluorobenzoic acid (C15H13FO4) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. 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).
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), 3-(2,4-Dimethoxyphenyl)-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.
