Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Fluoro-5-(4-fluoro-2-methylphenyl)benzoic acid (CAS 1178482-85-3), molecular formula C14H10F2O2 and molecular weight 248.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-5-(4-fluoro-2-methylphenyl)benzoic acid (C14H10F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic 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.
CATO manufactures 2-Fluoro-5-(4-fluoro-2-methylphenyl)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
