Chemical Structure
Description
4-((2-Chloro-6-fluorobenzyl)oxy)-3-methoxybenzoic acid (CAS 773872-82-5), molecular formula C15H12ClFO4 and molecular weight 310.70 g/mol, is a CATO reference standard with documented purity and traceability.
4-((2-Chloro-6-fluorobenzyl)oxy)-3-methoxybenzoic acid (C15H12ClFO4) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-((2-Chloro-6-fluorobenzyl)oxy)-3-methoxybenzoic 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.
